Ramp Integration Guide

Integrate Ramp spend, card, reimbursement, bill, and organizational data with enterprise systems through REST APIs, selected webhook events, and OAuth 2.0.

Ramp integration options at a glance

Ramp provides a versioned REST API for Users, Cards, Transactions, Departments, Reimbursements, Bills, spend programs, and related accounting data. OAuth 2.0 bearer tokens, organization permissions, and resource-specific scopes control access. Selected Ramp events can generate webhook-style notifications, although coverage varies by resource and state transition. Collection endpoints and pagination support incremental synchronization, while a general-purpose bulk export API is not confirmed. Receipt or document retrieval may be available for supported objects, but broad file APIs should not be assumed. Martini can orchestrate authenticated API calls, webhook workflows, pagination, checkpoints, mappings, validation, retries, reconciliation, and downstream writes.

Integration pointSupported by Ramp?Common use casesHow Martini supports it
REST APIsYesRetrieve Users, Cards, Transactions, Departments, Reimbursements, Bills, spend programs, and accounting-related data using the versioned Ramp API.Martini can consume the Ramp REST API from workflows, manage request configuration, transform responses, apply business rules, and invoke downstream APIs.
Webhooks / outbound callbacksLimitedReceive notifications for selected Ramp API events when the relevant resource and event are covered by Ramp's webhook capability.Martini can expose webhook endpoints, validate and persist notifications, deduplicate event IDs, retrieve the current Ramp object, and process retries or out-of-order delivery.
Bulk / asynchronous / batch APIsLimitedRamp supports collection endpoints and pagination for larger reads, but a general-purpose bulk export or asynchronous batch API was not confirmed.Martini can implement paginated incremental workflows with checkpoints, controlled concurrency, resumable processing, and reconciliation instead of assuming a single bulk request.
AuthenticationYesRamp applications use OAuth 2.0 bearer tokens, organization authorization, scopes, and permissions to access API resources.Martini can store protected configuration and secrets, consume OAuth-protected endpoints, handle token expiration and refresh, and separate environment credentials.
File / attachment APIsLimitedReceipt or transaction-related documents may be available for supported objects and account configurations; broad file import and export coverage was not confirmed.Martini can process documents only when the required Ramp endpoint exposes them, then route or store the content using an explicitly designed workflow.
Scheduled synchronizationYesScheduled polling is appropriate for incremental retrieval, reconciliation, and resources without applicable webhook coverage.Martini can trigger workflows on a schedule, persist per-resource checkpoints, paginate API calls, and retry or reconcile incomplete runs.
Database / analytics accessNoNo direct Ramp database, JDBC interface, or general-purpose analytics database access was confirmed.Martini should use Ramp's documented API or supported exports and can write normalized results to an approved downstream database or data platform.

How Ramp exposes data and business events

Ramp REST APIs

Ramp's versioned REST API is the primary integration mechanism for retrieving spend-management and finance data, including Users, Cards, Transactions, Departments, Reimbursements, and Bills. Access is controlled by OAuth 2.0 bearer tokens, organization authorization, scopes, and permissions.

Martini implementation pattern

Martini implementation pattern: Martini workflows authenticate against the configured Ramp API, call the required resource endpoints, follow pagination, transform the response into a canonical model, apply financial and organizational rules, and write the result to downstream applications or data platforms.

Implementation sequence

Authorize the Ramp application with the required scopes and permissions
Obtain or refresh the OAuth 2.0 access token
Call the required Ramp resource endpoint
Follow pagination and retain the resource checkpoint
Map the response into the target data model
Apply state, accounting, currency, and duplicate rules

Ramp Webhook Events

Ramp supports webhook-style notifications for selected API events. Coverage is resource- and event-specific, so notifications should not be assumed for every object or state transition, and event payloads may not contain the complete current object.

Martini implementation pattern

Martini implementation pattern: Martini exposes a controlled webhook endpoint, validates the incoming request according to Ramp's requirements, acknowledges accepted events promptly, stores event identifiers, and retrieves the current Ramp resource before downstream processing when necessary.

Implementation sequence

Receive the Ramp webhook notification
Validate the webhook request according to Ramp requirements
Persist the event identifier and raw notification metadata
Return a prompt success response for accepted events
Retrieve the current Ramp object when the payload is incomplete
Apply idempotency and process the downstream action

Ramp Pagination and Incremental Retrieval

Ramp collection endpoints support pagination for larger reads. A general-purpose bulk export or asynchronous batch API was not confirmed, so larger synchronizations should use incremental retrieval, checkpoints, and controlled concurrency.

Martini implementation pattern

Martini implementation pattern: Martini schedules resource-specific workflows, stores the last successful cursor or supported time position, processes pages in bounded batches, and resumes after partial failures without reposting completed objects.

Implementation sequence

Start the scheduled synchronization workflow
Load the checkpoint for the selected Ramp resource
Request the next page using supported pagination parameters
Transform and persist the returned objects
Advance the checkpoint only after successful downstream writes
Record reconciliation totals and retry eligible failures

Common Ramp integration patterns

Pattern 1: Sync Ramp spend to an accounting platform

When to use this pattern

Use this pattern when approved Ramp Transactions, Reimbursements, Bills, and accounting classifications must be posted to a general ledger or accounts-payable platform. The workflow should distinguish eligible financial states from pending or rejected objects.

Integration direction
Ramp
Martini
NetSuite
Example Mapping
Ramp FieldCanonical FieldTarget Field
transaction_idsourceTransactionIdexternalId
amountgrossAmounttransactionAmount

department_iddepartmentIddepartment
Martini implementation pattern

A scheduled Martini workflow retrieves eligible Ramp objects with pagination, validates accounting periods, currency, approval state, and deterministic keys, then maps and upserts the target accounting objects. Failed writes are isolated for bounded retry and reconciliation, while source and downstream IDs are retained for auditability.

Martini capabilities used
  • workflows
  • API consumption
  • scheduling
  • pagination and checkpointing
  • data mapping
  • business rules
  • error handling

Pattern 2: Process Ramp webhook notifications

When to use this pattern

Use this pattern for selected Ramp events where near-real-time notification is useful for finance operations, approvals, exceptions, or downstream notifications. Because webhook coverage is partial, scheduled reconciliation should supplement the event flow.

Martini implementation pattern

Martini receives the webhook, validates it, persists the event ID, and checks whether it has already been processed. It retrieves the current Ramp object when required, applies routing and notification rules, calls the downstream API, and sends uncertain or failed events to a retry and reconciliation path.

Martini capabilities used
  • APIs
  • webhook consumption
  • workflows
  • idempotency rules
  • data enrichment
  • conditional routing
  • error handling

Pattern 3: Synchronize employees and departments

When to use this pattern

Use this pattern when an HR or identity platform is authoritative for employee status, department membership, or manager relationships used by Ramp administration. The field authority and update direction should be agreed before deployment.

Martini implementation pattern

A scheduled workflow retrieves source employee and organizational data, compares it with Ramp Users and Departments, applies inactive-user and authority rules, and submits only supported changes. Martini records source and target identifiers, reports mismatches, and avoids repeated updates through deterministic comparison keys.

Martini capabilities used
  • scheduled workflows
  • API consumption
  • data mapping
  • validation
  • business rules
  • idempotent synchronization
  • audit logging

Pattern 4: Load Ramp spend data into a warehouse

When to use this pattern

Use this pattern when finance teams need normalized Transactions, Cards, Departments, Users, and Reimbursements for reporting, reconciliation, and spend analytics. It is suitable when the target model requires historical source metadata and repeatable incremental loads.

Martini implementation pattern

Martini retrieves each resource incrementally, follows pagination, normalizes object structures and monetary values, and loads the result with ingestion timestamps and source identifiers. Checkpoints advance only after successful writes, while counts, totals, and rejected rows are retained for reconciliation.

Martini capabilities used
  • workflows
  • scheduling
  • REST API consumption
  • pagination
  • data transformation
  • database or data-platform writes
  • monitoring

Applications commonly integrated with Ramp

Ramp data can be connected to accounting, HR, identity, collaboration, and analytical platforms through Martini workflows. The exact direction and object coverage should be defined around the authoritative source, Ramp permissions, and the target application's API capabilities.

Application Scenario Direction Martini Pattern
NetSuite Synchronize Ramp Transactions, Reimbursements, Bills, Users, Departments, and accounting classifications with the general ledger and accounts-payable processes. Ramp → Martini → NetSuite Use scheduled or event-assisted REST API workflows to retrieve approved or eligible Ramp objects, apply accounting-period and duplicate controls, map dimensions and classifications, and post or upsert the target records through NetSuite APIs.
QuickBooks Online Post approved Ramp spend and reimbursement information into a small- or mid-market accounting environment. Ramp → Martini → QuickBooks Online Retrieve Ramp data incrementally, normalize monetary values and currency codes, map categories and departments to QuickBooks Online structures, and route rejected writes to a retry and reconciliation workflow.
Sage Intacct Transfer corporate-card, reimbursement, bill, and dimensional accounting data into financial-management workflows. Ramp → Martini → Sage Intacct Orchestrate paginated Ramp reads, validate financial states and accounting periods, transform dimensions and classifications, and submit the resulting payloads using the target platform's supported APIs.
Workday Synchronize employee identity, employment status, manager, and department information used for Ramp user and spend administration. Workday → Martini → Ramp Run a controlled HR-to-Ramp synchronization that compares Users and Departments, applies authority rules for employee status and organizational assignments, and records source and target identifiers for reconciliation.
Rippling Keep employee and organizational data aligned between HR administration and Ramp. Rippling → Martini → Ramp Consume supported Rippling data, map employee and department attributes to Ramp objects, validate required permissions and assignments, and use idempotent updates with exception reporting.
BambooHR Provision or update Ramp Users and organizational assignments from employee records. BambooHR → Martini → Ramp Schedule employee synchronization, transform BambooHR identity and department fields, apply inactive-user and duplicate rules, and submit supported Ramp API operations with audit metadata.
Slack Send selected spend, approval, exception, or finance notifications to operational channels. Ramp → Martini → Slack Receive supported Ramp webhook notifications or detect changes through polling, enrich the event by retrieving the current Ramp object, apply notification rules, and call Slack only after deduplication.
Snowflake Load normalized Ramp transaction and reimbursement data for reporting, reconciliation, and spend analytics. Ramp → Martini → Snowflake Use checkpointed pagination to retrieve incremental Ramp data, preserve source identifiers and timestamps, normalize objects into analytical structures, and load batches with reconciliation metrics.

Authentication and security considerations

OAuth 2.0 and permissions

Ramp uses OAuth 2.0 bearer-token authentication. Applications must be authorized for the relevant Ramp organization, and access depends on resource-specific scopes and organization permissions.

  • Store client credentials and access or refresh tokens in protected configuration rather than workflow payloads or logs.
  • Request only the permissions required for Users, Cards, Transactions, Departments, Reimbursements, Bills, or other selected resources.
  • Handle token expiration and refresh in the integration runtime.
  • Separate development, test, and production credentials and validate administrator approval before deployment.

Webhook security

Validate incoming Ramp webhook requests according to Ramp's documented requirements, acknowledge accepted events promptly, and persist event identifiers for deduplication and auditability.

Operational considerations for Ramp integrations

Reliability and synchronization

  • Follow pagination and persist independent checkpoints for resources such as Transactions, Reimbursements, and Bills.
  • Use bounded exponential backoff for transient failures and avoid indefinite retries for invalid requests or authentication failures.
  • Use event IDs and source-object IDs for idempotency because webhook delivery and scheduled polling can overlap.
  • Retrieve the current object after a notification when the event payload is incomplete or may arrive out of order.
  • Preserve currency codes and decimal precision, and apply explicit rules for pending, approved, rejected, settled, reimbursed, or changed financial states.
  • Use tolerant parsing for optional fields, new enum values, and API version changes.
  • Run periodic reconciliation of counts, totals, statuses, and updated timestamps even when webhooks are enabled.
  • Retain source IDs, workflow execution identifiers, timestamps, and downstream references for finance auditability.

Why use Martini instead of scripts or point-to-point integrations?

Beyond point-to-point scripts

Martini provides a governed workflow layer for Ramp integrations rather than requiring separate scripts for every target system. It can centralize OAuth configuration, pagination, checkpoints, webhook handling, mapping, validation, business rules, retries, and monitoring.

  • Reuse API and transformation logic across accounting, HR, notification, and data-platform workflows.
  • Combine event-driven processing with scheduled synchronization and reconciliation when Ramp webhook coverage is selective.
  • Apply consistent idempotency, financial-state, currency, and error-handling rules across downstream systems.
  • Expose controlled APIs for internal consumers without distributing Ramp credentials or implementation details.
  • Maintain deployable integration assets that can evolve as Ramp resources, target schemas, and business rules change.

Frequently asked questions

How can Ramp be integrated with enterprise systems?

Ramp can be integrated through its versioned REST API using OAuth 2.0 bearer tokens, organization authorization, scopes, and resource permissions. Selected Ramp events can also produce webhook-style notifications, while scheduled, paginated API retrieval supports synchronization and reconciliation.

Can Martini integrate with Ramp?

Yes. Martini can consume the Ramp REST API, manage OAuth 2.0 configuration and secrets, receive supported Ramp webhook events, orchestrate scheduled synchronization, transform Ramp objects, and write results to accounting, HR, notification, or data platforms.

Do I need a connector to integrate Ramp with Martini?

No. A dedicated Ramp connector is not required. Martini can integrate using Ramp's confirmed native mechanisms, including its REST API, OAuth 2.0 authentication, selected webhook events, and paginated collection endpoints.

Is there any extra Lonti cost to integrate Ramp with Martini?

Lonti does not charge an additional per-connector or per-vendor fee to integrate Ramp. The integration is subject to the provisioned capacity of the Martini environment. Separate costs may apply from Ramp, cloud infrastructure, accounting platforms, data platforms, or other third-party services depending on subscriptions, usage, and deployment choices.

Which Ramp integration methods should architects use?

The documented versioned REST API should be the primary mechanism for new integrations. Use OAuth 2.0 with the minimum required permissions, selected webhooks for supported events, and scheduled paginated retrieval for incremental synchronization and reconciliation. GraphQL and SOAP were not confirmed for the public Ramp API.

Are Ramp webhooks available for event-driven integrations?

Ramp provides webhook-style notifications for selected API events, but coverage is resource- and event-specific. Martini can receive and process those notifications, validate and deduplicate them, retrieve the current object when needed, and supplement event processing with scheduled reconciliation.

How does synchronization with Ramp handle mapping and duplicates?

Martini can map Ramp Users, Cards, Transactions, Departments, Reimbursements, and Bills into canonical and target-specific models. Checkpoints, source identifiers, event IDs, deterministic upsert keys, and financial-state rules help prevent duplicate writes and support resumable synchronization.

Can Martini expose an API façade for Ramp data?

Yes. Martini can expose a controlled API that provides a governed internal interface over selected Ramp data or workflows. The façade can centralize authentication, validation, mapping, business rules, rate control, and error handling without exposing Ramp credentials to every consuming application.
