# Update contacts

Use the **Update Contacts** API to update existing contacts/leads in a live [Dialer campaign](https://docs.voiso.com/docs/outbound-dialer-campaign-launching-your-campaign#live-campaign). Contacts are identified by their phone number. You can only update the contact name, source, URL, active state, and priority. The API endpoint description is [here](/v1-api/apidocs/update-contacts).

## Prerequisites

- The [Dialer campaign](https://docs.voiso.com/docs/outbound-dialer-campaign-launching-your-campaign#live-campaign) must have the **Live campaign** setting enabled.
- The campaign ID, which can be obtained by using [List Campaigns](/v1-api/apidocs/docs-list-campaigns) API request or from the **Outbound > Campaigns** page.
- A valid phone number for each contact in [E.164 format](https://www.itu.int/rec/T-REC-E.164) without the preceding '+'. For example: `441234567890`.

| isActive | An indicator of whether the contact should be dialed as part of the campaign. | number | Optional | Valid values are 0 and 1. 0 means the contact should not be called. 1 means the contact should be called. |

## Troubleshooting

The following issues are sometimes encountered:

### Invalid Key

The **Add Contacts** API requires the user API key to validate the request. If you see this error, `"error": "Invalid Key"`, check that you are using the correct user API key. For more information about API keys, refer to [Authentication](/v1-api/apidocs/authentication).

### Campaign not found

If you see this error, `"error": "Campaign not found"`, the campaign ID that you specified in the request URL does not exist in your contact center or is not accessible to the user.

To verify the campaign ID, use the [List Campaigns](/v1-api/apidocs/docs-list-campaigns) API to request it, or from the **Outbound > Campaigns** page, find the campaign ID in the **Campaigns** table.

To verify that the user has access to the specified campaign, check the [user profile](https://docs.voiso.com/docs/users-users) associated with the API request. The **Edit all campaigns** or **Edit own campaigns** [permissions](https://docs.voiso.com/v1/docs/administration-security-access-groups#outbound) must be assigned to the user's profile.

### Campaign type should be live

If you see this error, `"error": "Campaign type should be live"`, the **Live campaign** option is not enabled for the specified campaign. To set this option, from the Voiso main menu bar, navigate to **Outbound > Dialer campaigns** and select the campaign. On the **Edit campaign** page, select **Live campaign** and save the campaign.

### Maximum limit of 1000 contacts for each request

If you see this error, `"error": "Maximum limit of 1000 contacts for each request"`, your POST request is attempting to add more than 1000 contacts to the campaign. To add more than 1000 contacts, make multiple requests of up to 1000 contacts each.

### Required contact field missing

If you see this error, `"error": "Required contact field missing - phoneNumber"`, there is no phone number available for one or more of the contacts you are trying to add to the campaign. Please ensure that you have a phone number for every contact you add to the campaign.
