Sovos Integration Guide

Connect Sovos tax, e-invoicing, transaction, and compliance services with enterprise systems through product-specific APIs, callbacks, workflows, and file exchange.

Sovos integration options at a glance

Sovos integrations are product- and tenant-specific, with REST APIs as the primary approach for submitting transactions, invoices, orders, and tax data, retrieving compliance results, and managing related configuration. Selected products may also provide webhook-style callbacks, asynchronous or batch processing, report retrieval, file exchange, or legacy SOAP interfaces. Authentication can involve API credentials, API keys, OAuth 2.0, client credentials, access tokens, and tenant permissions. Martini can consume the applicable Sovos endpoints, expose internal APIs, orchestrate asynchronous workflows, map and transform JSON or file data, receive documented callbacks, and use scheduled polling when event coverage is unavailable.

Integration pointSupported by Sovos?Common use casesHow Martini supports it
REST APIsYesSubmit transactions, invoices, orders, and tax requests; retrieve calculations, compliance results, statuses, products, customers, or configuration. Coverage varies by Sovos product and tenant.Martini can consume documented Sovos REST endpoints, manage authenticated requests, transform payloads, and expose reusable internal APIs.
AuthenticationYesSovos APIs require secured access, potentially using API credentials, API keys, OAuth 2.0, client credentials, tokens, and tenant or company permissions.Martini stores credentials and product-specific settings in secure environment configuration and applies the required authentication pattern.
Webhooks / outbound callbacksLimitedSelected products may notify clients about document statuses, asynchronous jobs, validation results, or compliance processing events.Martini can expose an HTTPS API to receive documented callbacks, validate requests, apply idempotency, and start workflows; otherwise it can poll statuses.
Bulk / async / batch APIsLimitedSelected Sovos products may support bulk submissions, asynchronous processing, or report-generation jobs.Martini can submit a job, persist the Sovos job identifier, poll for completion, and route successful, rejected, and retryable outcomes.
File / attachment APIsLimitedSome Sovos compliance products and legacy processes support file exchange or report downloads, with formats and delivery channels varying by product and jurisdiction.Martini can orchestrate supported file ingestion or export, validate formats, transform content, and reconcile file-level results.
SOAP APIsLimitedSome legacy or product-specific Sovos interfaces may expose SOAP services, but SOAP coverage is not universal across the portfolio.Martini can consume a confirmed Sovos SOAP service when required, while REST should generally be preferred for current documented APIs.
SDKsLimitedSovos may provide product-specific SDKs or sample libraries, but SDK availability is not consistent across the portfolio.Martini can use the underlying HTTPS API or custom JVM-compatible logic when an SDK is not directly suitable.
Database accessNot confirmedDirect access to Sovos-managed production databases was not confirmed and should not be assumed.Martini should use Sovos-provided APIs, reports, callbacks, or supported file exchange rather than direct database connectivity.

How Sovos exposes data and business events

Sovos REST APIs

REST is the primary confirmed integration mechanism for Sovos products that expose public APIs. Product-specific endpoints can support submissions, tax requests, configuration, status queries, and compliance results, with authentication and object coverage varying by tenant.

Martini implementation pattern

Martini implementation pattern: a workflow or Martini API receives an enterprise request, authenticates against the selected Sovos API, maps the canonical model to the Sovos contract, processes the response, and stores identifiers for later reconciliation.

Implementation sequence

Receive an invoice, transaction, order, or tax request
Load the product-specific Sovos endpoint and credentials
Map and validate the request against the Sovos schema
Call the Sovos REST endpoint over HTTPS
Interpret the response and persist the Sovos reference
Return the result or route it to asynchronous reconciliation

Sovos callbacks

Some Sovos products may provide outbound callbacks or notifications for selected document statuses, asynchronous jobs, validation results, or compliance events. Coverage is product- and event-specific.

Martini implementation pattern

Martini implementation pattern: expose a secured HTTPS API for the documented callback, validate the notification, apply idempotency controls, retrieve the current Sovos resource when necessary, and start a downstream workflow.

Implementation sequence

Receive the documented Sovos callback
Authenticate and validate the notification
Check the event or submission identifier for duplicates
Retrieve the current Sovos status when required
Map the result to the target system model
Persist the event and update the source system

Sovos asynchronous processing

Selected Sovos products may process bulk submissions, compliance documents, or reports asynchronously. A submission can acknowledge receipt without representing final acceptance.

Martini implementation pattern

Martini implementation pattern: submit the Sovos job, persist its identifier and source business key, then use a documented callback or scheduled workflow to retrieve completion status and route accepted, rejected, or retryable results.

Implementation sequence

Submit the Sovos document or batch job
Persist the Sovos job identifier and source key
Wait for a callback or scheduled status check
Retrieve the completed result or error details
Apply status and business-rule mappings
Reconcile the final outcome with the originating system

Sovos file exchange

Some Sovos compliance products and legacy processes support file exchange or report downloads. Formats, schedules, delivery channels, and jurisdictional requirements vary by product.

Martini implementation pattern

Martini implementation pattern: a workflow obtains or receives the supported file, validates its structure, parses the content, maps rows or documents to the internal model, and records reconciliation results.

Implementation sequence

Receive or retrieve the supported Sovos file
Validate the file format and product context
Parse records or report contents
Map data to the target canonical model
Write results to the destination system
Record file-level reconciliation and exceptions

Sovos SOAP services

Some legacy or product-specific Sovos interfaces may expose SOAP services, although current portfolio-wide coverage was not confirmed. REST should be preferred when an equivalent current API exists.

Martini implementation pattern

Martini implementation pattern: where a Sovos SOAP contract is confirmed, Martini consumes the service with the required authentication, transforms XML messages, handles SOAP faults, and isolates the legacy interface behind a reusable workflow or API.

Implementation sequence

Confirm the Sovos SOAP contract and endpoint
Configure the required authentication and XML settings
Map the canonical request to the SOAP message
Invoke the Sovos service and inspect SOAP faults
Transform the response into the internal model
Persist the result and apply retry rules

Common Sovos integration patterns

Pattern 1: Submit ERP invoices to Sovos

When to use this pattern

Use this pattern when an ERP produces approved invoices that must be validated, cleared, reported, or processed through a Sovos e-invoicing or compliance product. It supports synchronous acknowledgement followed by asynchronous status reconciliation.

Example Mapping
Sovos FieldCanonical FieldTarget Field
invoiceNumberdocument.numberInvoiceNumber
customer.taxRegistrationcustomer.taxRegistrationBuyerTaxRegistration
lines[].taxAmountlines[].tax.amountInvoiceLines[].TaxAmount
currencydocument.currencyCurrencyCode
Martini implementation pattern

Martini receives the approved invoice, validates required country and registration fields, maps it to the selected Sovos contract, submits it, and stores the Sovos identifier. A follow-up workflow polls or receives a callback for final clearance, rejection, or reporting status. Duplicate keys and transient failures are handled separately from confirmed business rejections.

Martini capabilities used
  • workflows
  • API consumption
  • data mapping
  • business rules
  • error handling
  • scheduled synchronization

Pattern 2: Calculate tax during order processing

When to use this pattern

Use this pattern when a commerce or order system needs a Sovos tax result before confirming an order, shipment, or invoice. The flow should prioritize predictable latency, consistent rounding, and reliable retry behavior.

Martini implementation pattern

A Martini API façade accepts a normalized tax request, enriches it with product classification and exemption information, calls the Sovos tax endpoint, and returns a stable response to the commerce platform. Martini applies timeout, retry, rounding, and validation rules without exposing product-specific Sovos details to the caller.

Martini capabilities used
  • APIs
  • API consumption
  • data transformation
  • business rules
  • error handling

Pattern 3: Reconcile Sovos compliance statuses

When to use this pattern

Use this pattern when Sovos processing is asynchronous or when callbacks are unavailable for the required event. It keeps ERP, finance, or monitoring systems aligned with accepted, rejected, pending, and errored submissions.

Integration direction

Example Mapping
Sovos FieldCanonical FieldTarget Field
submissionIdcompliance.externalReferenceSovosReference
statuscompliance.statusInvoiceComplianceStatus
errors[].codecompliance.issues[].codeValidationErrorCode
processedAtcompliance.completedAtProcessedTimestamp
Martini implementation pattern

A scheduled Martini workflow retrieves changed statuses using the documented pagination and filtering model, persists a cursor or last-processed timestamp, maps Sovos statuses and errors to the target system, and records audit references. Idempotency checks prevent repeated updates, while transient failures are retried without resubmitting confirmed documents.

Martini capabilities used
  • scheduled workflows
  • API consumption
  • pagination handling
  • data mapping
  • idempotency
  • error handling

Pattern 4: Process ShipCompliant orders and shipments

When to use this pattern

Use this pattern for Sovos ShipCompliant scenarios where an e-commerce or order-management platform submits products, companies, orders, and shipments for alcohol-industry compliance processing. Exact operations must be confirmed against the ShipCompliant API available to the tenant.

Integration direction

Martini implementation pattern

Martini validates product, company, customer, and destination data, maps orders and shipments to the confirmed ShipCompliant operations, and returns compliance decisions or processing references to the source. Duplicate order keys, jurisdiction restrictions, asynchronous responses, and rejected shipments are routed through explicit business and retry paths.

Martini capabilities used
  • workflows
  • API consumption
  • data mapping
  • conditional routing
  • business rules
  • error handling

Applications commonly integrated with Sovos

Authentication and security considerations

Product-specific authentication

Sovos authentication varies by product and tenant. Depending on the API, access may use API credentials, API keys, OAuth 2.0, client credentials, access tokens, and tenant, company, or account permissions.

Secure Martini configuration

  • Store Sovos credentials, client secrets, tenant identifiers, and base URLs in Martini secrets or secure environment configuration.
  • Use TLS-secured HTTPS for REST and callback integrations.
  • Confirm scopes, required headers, token endpoints, permission boundaries, and credential rotation procedures with the selected Sovos product.
  • Restrict logs and stored payloads because invoices and tax data may contain customer, address, financial, and regulatory information.

Operational considerations for Sovos integrations

Portfolio and tenant variation

Confirm the exact Sovos product, API family, region, sandbox, production endpoint, object model, and current or legacy contract before implementation.

Throughput and retrieval

Verify product-specific rate limits, concurrency rules, pagination, and filtering. Martini workflows can throttle requests, persist cursors or timestamps, and use scheduled or asynchronous execution for reconciliation.

Idempotency and asynchronous processing

Use stable invoice, transaction, order, or shipment keys and store Sovos identifiers. A successful submission may acknowledge receipt rather than final acceptance, so callbacks or status polling may be required.

Regulatory change and testing

Version Sovos mappings and isolate product-specific transformations as schemas, tax codes, registration requirements, and validation rules change. Test authentication, validation failures, duplicate submissions, timeouts, rate limits, and status transitions in an appropriate environment.

Audit and error handling

Separate transient transport failures from business rejections and retain the Sovos reference, response status, and relevant error details for reconciliation without exposing secrets.

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

Orchestration across systems

Martini coordinates Sovos API calls, source-system events, callbacks, scheduled polling, file processing, and downstream updates in explicit workflows rather than scattering logic across scripts.

Reusable integration assets

Martini can expose APIs that abstract product-specific Sovos behavior, reuse authentication and response-handling logic, and maintain canonical mappings across ERP, commerce, finance, and reporting systems.

Controlled transformation and resilience

Workflows apply validation, business rules, idempotency, retries, asynchronous processing, and error routing while keeping Sovos-specific schemas isolated from internal data models.

Operational maintainability

Centralized configuration, workflow monitoring, logging, and versioned mappings make it easier to adapt to product, jurisdiction, and regulatory changes than a collection of unmanaged point-to-point scripts.

Frequently asked questions

How can Sovos be integrated with enterprise systems?

Sovos can be integrated through its product-specific REST APIs, authenticated HTTPS requests, selected callbacks or webhook-style notifications, asynchronous or batch processing, supported file exchange, and some legacy SOAP interfaces. The correct mechanism depends on the Sovos product, tenant, region, and business process.

Can Martini integrate with Sovos?

Yes. Martini can integrate with Sovos by consuming the relevant Sovos REST API, orchestrating asynchronous submissions and status queries, receiving documented callbacks, processing supported files, or consuming a confirmed SOAP interface. No native Martini Sovos connector was confirmed in the supplied information.

Do I need a connector to integrate Sovos with Martini?

No. A dedicated Sovos connector is not required. Martini can use Sovos native APIs, authentication methods, callbacks, asynchronous status endpoints, supported file exchange, or confirmed legacy services, with workflows handling mapping, orchestration, and error processing.

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

Lonti does not charge an additional per-connector or per-vendor fee to integrate Sovos. The integration is subject to the provisioned capacity of the Martini environment. Separate costs may apply from Sovos, cloud infrastructure, or other third-party systems based on subscriptions, usage, and deployment model.

Which Sovos integration method should architects use?

REST should generally be the default where the selected Sovos product provides a current API. Callbacks or webhook-style notifications can be used when documented for the required events, while scheduled polling supports products without adequate event coverage. SOAP may be relevant for legacy or product-specific services, and GraphQL was not confirmed.

Does Sovos support events or webhooks?

Some Sovos products may provide outbound callbacks or status notifications for selected documents, jobs, validation results, or compliance events. Coverage is not universal across the Sovos portfolio, so the selected product documentation must be checked. Martini can receive documented callbacks or poll the relevant status endpoint.

How does Martini synchronize Sovos data with an ERP?

Martini can submit ERP invoices, transactions, orders, or tax data to Sovos, store Sovos references, and reconcile accepted, rejected, pending, or errored statuses through callbacks or scheduled workflows. Pagination, cursors, timestamps, business keys, and idempotency controls support incremental synchronization.

How are Sovos errors, retries, duplicates, and mappings handled?

Martini can validate and transform Sovos payloads, separate authentication, transport, rate-limit, schema, and business-rule errors, retry only transient failures, and preserve rejected payload details for review. Stable source keys and stored Sovos identifiers help prevent duplicate submissions, while mappings can be versioned as tax and regulatory schemas change.
