Frequently Asked Questions

What is the Contacts API?

The Contacts API is a RESTful interface that lets you manage your contact data. It supports reading, creating, updating, and deleting contacts, as well as related entities like tasks and notes. This guide shows how to connect Doppler to the API and automate common workflows. In practice, you’ll configure authentication, select endpoints, and set up data flows to keep records in sync.

No heavy coding is required for a basic connection using the provided endpoints and authentication methods. However, some light scripting may help map fields and handle retries, especially when dealing with field name differences or nested objects.

Typical endpoints for syncing include GET /contacts/:contactId to read a contact, POST /contacts/ to create, and PUT /contacts/:contactId to update. For related data like tasks and notes, use GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and related paths as needed.

Use OAuth 2.0 or API keys as supported, rotate credentials, and store secrets securely. Apply least-privilege scopes (e.g., contacts.readonly) until you’re ready to write data. Refresh tokens regularly and monitor for unusual activity.

Yes. The API includes endpoints for tasks, notes, and notes attached to contacts. You can set up Doppler triggers to sync these items to ensure up-to-date records across both systems.

Test using a sandbox or staging environment if available. Validate data mapping, run end-to-end tests, and monitor API responses and logs to catch errors before going live.

Error logs appear in the integration dashboard or your app’s logging system. Check HTTP status codes, response messages, and retry events to diagnose issues and adjust mappings or credentials.
