Authenticate requests using OAuth 2.0 tokens with the required scope: contacts.readonly. Include the token in the Authorization header as Bearer
Configure Fattura24 to securely call the Contacts API by using its API key or OAuth client credentials. Keep tokens refreshed and stored securely, and rotate credentials regularly.

The Contacts API supports OAuth 2.0 with access tokens. You can also use API keys for read-only access within the specified scope (contacts.readonly). Include the Authorization header: Bearer
For basic sync, focus on endpoints like GET /contacts/:contactId and GET /contacts/ to read and list contacts. For creating or updating, use POST /contacts/ and PUT /contacts/:contactId. Map fields carefully (name, email, phone) to ensure idempotent operations and prevent duplicate records.
Yes. Use a test or staging environment to validate flows before going live. Utilize sandbox credentials if available and mock data to simulate real-world scenarios. Review logs and data mappings to avoid impacting production data.
The API uses JSON for requests and responses. Payloads should include fields like name, email, phone, and related IDs. Responses return standard HTTP status codes and a JSON body with data or error details to aid debugging.
There are rate limits that apply to requests; if you exceed, you may receive 429 responses. Plan polling carefully and prefer webhooks to reduce polling. If you anticipate higher usage, request a higher limit from support.
When errors occur, review the HTTP status code, error message, and any error codes in the response body. Implement retry logic with exponential backoff and respect Retry-After headers when provided.
Official API documentation and examples are available on the developer portal, including endpoints, authentication details, and code samples. For additional help, contact support or your account manager.
Due to high volume, we will be upgrading our server soon!
