This page gathers every Relate API resource endpoint in one place. For common topics such as authentication, base URL, and pagination, see the Introduction.

​

Read, create, update, and delete contacts.

​
List all contacts

curl https://api.relate.so/v1/contacts \

curl -X GET "https://api.relate.so/v1/contacts?email=email@email.com" \
  -H "Authorization: Bearer {api_key}" \
  -H "Accept: application/json"
Or by phone number. The number is normalized the same way it is stored, so any common format — +821012345678, 01012345678, 010-1234-5678 — matches the same contact.
