# Update metadata for campaign contacts

`PATCH /campaigns/call/{campaignscalllistuuid}/numbers`

Updates the metadata (`json_csv_infos`) of one or more contacts already in a campaign's call queue. Use this to modify contact information (firstname, lastname, company, custom fields) without removing and re-adding the contacts. Each entry in the `to_numbers` array must include the `to_number` (phone number) to identify the contact and the updated `json_csv_infos` object.

**Permission:** No specific permission required. A valid API key is sufficient.

    - `json_csv_infos` string, json — Contains data related to the number. json_csv_infos must follow the schema: {"company": "", "firstname": "", "lastname": "", "social_data": [{"optionalField": ""}, ...]} The fields "company", "firstname", "lastname" and "social_data" are required.
