    Update an Email Template

    This API is used to update an existing Email Template.

    You must specify the Id of the Email Template you are updating on the URI.

    You must specify all of the properties of the Email Template when calling this API with the PUT HTTP method. When used with PUT, this API doesn’t merge the existing Email Template and your new data. It replaces the existing Email Template with your new data.

    Utilize the PATCH HTTP method to send specific changes to merge into an existing Email Template.

    Request

    Update an Email Template by Id

    URI

    PUT /api/email/template/{emailTemplateId}

    PATCH /api/email/template/{emailTemplateId}

    Available since 1.39.0

    When using the PATCH method, you can either use the same request body documentation that is provided for the PUT request for backward compatibility. Or you may use either JSON Patch/RFC 6902 or JSON Merge Patch/RFC 7396. See the PATCH documentation for more information.

    Available since 1.12.0

    When using the PATCH method, use the same request body documentation that is provided for the PUT request. The PATCH method will merge the provided request parameters into the existing object, this means all parameters are optional when using the PATCH method and you only provide the values you want changed. A null value can be used to remove a value. Patching an Array will result in all values from the new list being appended to the existing list, this is a known limitation to the current implementation of PATCH.
