TriggeredSend SOAP API Permission Changes in Salesforce

If you have installed packages that use the SOAP API to send email, update their permission scopes.

1. From Setup, in the Quick Find box, enter Installed Packages, and then select Installed Packages.

2. Select the package to modify.

3. In the Components section, click the Edit button for your integration.

4. In the Channels section, under Email, select the Read, Write, and Send checkboxes.

Update API user permissions

If you use username and password authentication with SOAP API send triggered emails, update your user permissions.

Note: This step applies only to users with the API User setting enabled. If a user doesn’t have this setting enabled or doesn’t perform triggered email sends, no action is required. 

1. From Setup, in the Quick Find box, enter Users, and then select Users.

2. Select a user, and then click Manage Roles.

3. Select Edit Permissions.

4. In the Email | Interactions | Messages | Email section, next to Triggered, select Allow.

5. Save your changes.

Caution:
If you don't update the permissions by June 19, 2026, your Salesforce TriggeredSend SOAP API calls will not send emails and return an API Permission Failed error.
