API reference

Base URL

Send every request to https://api.hightouch.com/api/v1.

Authenticate with a Hightouch API key in the Authorization header as a bearer token:

curl https://api.hightouch.com/api/v1/syncs \
  -H "Authorization: Bearer <API_KEY>"

Each key belongs to one workspace and inherits the permissions of a user group. To create a key and choose its permissions, see the API overview.

Each endpoint page has an API playground. Enter your API key, fill in the parameters, and send the request to see the live response.
