Frequently Asked Questions

What authentication methods are supported for the Contacts API?

The Contacts API supports API keys and OAuth tokens. Use the scope ‘contacts.readonly’ for read-only operations and ensure your app has proper permissions. For production, store credentials securely and rotate keys regularly. When using OAuth, refresh tokens before expiry to maintain uninterrupted access.

For basic syncing, start with GET /contacts/:contactId to fetch contact data and GET /contacts/:contactId/tasks to pull associated tasks. You can create new contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. This forms the foundation of most workflows.

Implement exponential backoff on 5xx errors and respect any rate limits. Log failures with helpful context, map error codes to user-friendly messages, and aim for idempotent operations where possible to avoid duplicates.

Yes. You can create new contacts with POST /contacts/ and update existing records via PUT /contacts/:contactId. Deleting is done with DELETE /contacts/:contactId; consider soft-delete patterns if your app requires audit history.

Notes are read via GET /contacts/:contactId/notes and can be created or updated using the corresponding endpoints. Tags are managed with POST /contacts/:contactId/tags to organize contacts for segmentation and targeted campaigns in Thankster.

Rate limits vary by plan and endpoint. If you approach limits, back off and space requests. Batch operations when possible and monitor usage with your API dashboard to stay within quotas.

Endpoint references, field mappings, and example payloads are documented in your API docs and the connector guide. If you need a tailored data mapping, contact support for a consult or use Zapier to assist with mapping automation.
