Add contacts to a group

POST 
/api/v1/contacts/groups/:groupId/contacts

Feeds a group. The body carries a contacts array, not a bare list of numbers.

  • phone must contain digits only — no +, no space, no dash. Write 221771234567, not +221 77 123 45 67.
  • 1000 entries maximum per request. For larger volumes call this endpoint several times on the same group: contacts accumulate.
  • Sending a number already in the group does not duplicate it — its name and notes are updated instead.

Required capability: CAMPAIGNS
