Contact Management

Manage contacts and their channel associations in Sinch Conversation API using the Conversation API specification. Note: MCP tools do not provide contact management tools, so this skill always uses the Conversation API endpoints. Contacts represent end-users and can span multiple messaging channels.

Instructions

1. Identify the operation from user request:

   • Create contact: New contact with channel identity
   • Update contact: Modify contact information or add channels
   • List contacts: Retrieve contacts with optional filtering
   • Get contact: Retrieve specific contact details
   • Find contact: Search for contact by phone number, email, or ID

2. Extract contact information:

   • Contact identifier: phone number, email, contact ID, or name
   • Channel identities: WhatsApp, SMS, or other channels with identities
   • Display name: Contact's display name
   • Email: Contact's email address
   • Language: Preferred language code (e.g., EN_US)

3. Use Conversation API endpoints to perform operations:

   • Note: MCP Sinch does not provide contact management tools, so this skill always uses the Conversation API endpoints
   • Create contact:

     POST /v1/projects/{project_id}/contacts

     (Operation ID:

     Contact_CreateContact

     )
   • Update contact:

     PATCH /v1/projects/{project_id}/contacts/{contact_id}

     (Operation ID:

     Contact_UpdateContact

     )
   • Get contact:

     GET /v1/projects/{project_id}/contacts/{contact_id}

     (Operation ID:

     Contact_GetContact

     )
   • List contacts:

     GET /v1/projects/{project_id}/contacts

     (Operation ID:

     Contact_ListContacts

     )
   • Authentication: Use Basic Auth or OAuth2 with credentials from environment variables
   • Region: Use CONVERSATION_REGION environment variable (us, eu, or br)
   • Base URL:

     https://{region}.conversation.api.sinch.com

4. Response handling:

   • Confirm successful operations with contact ID
   • Display contact information clearly
   • Show associated channels for contacts
   • Report errors with actionable guidance

   page_size

   ,

   page_token

   ,

   external_id
