How to use the REST API
This article explains where to start when you want to use the Crisp REST API.
The REST API lets developers read and write Crisp data from a backend, plugin, or internal integration. Use it when you need to send messages, retrieve conversations, update people profiles, manage plugin settings, or automate workspace operations.
Before you start
You will need API credentials and the right token type for your use case. Development tokens are useful for testing from a trusted workspace, while production tokens are required once your integration is deployed.
Developer documentation
Use these Developer Hub resources:
- REST API quickstart → authentication, tokens, and first requests
- REST API reference → available endpoints, scopes, tiers, request bodies, and responses
- RTM API quickstart → useful when your REST actions need real-time acknowledgements or events
