Services

A Verification Service is the set of common configurations used to create and check verifications. You can create a service with the API or in the Console. Services include configuration for features like:

Email
Friendly Name (used in the Verification message templates, except in countries with brand restrictions)
Code Length
Skip sending SMS to Landlines
Requiring DTMF Input for Voice Verifications
Enabling Twilio Lookup

The SMS channel example below shows different friendly names and code lengths used in our SMS message templates.

Associate a predefined template with a service

A predefined template (public or private if there are any associated with your account) can be associated with a Verification Service by setting the DefaultTemplateSid attribute. By doing so, the message body of the verifications created with the service will use the text defined in the referenced template by default.

The default template SID<HJ> is a unique ID starting with the letters HJ. It is automatically generated when the template is created.

A complete list of the available templates for the account can be obtained by querying the Templates API.

The template that is going to be used in the verification will be selected in the following order:

If a TemplateSid is received in the Create Verification request, the verification will use the text defined in the template identified with that Sid.
If a DefaultTemplateSid is set for the Service, the verification will use the text defined in the template identified with that Sid.
Otherwise, the text defined in the global default template will be used.

Associate a template with an existing service

A predefined template can be associated with an already created Verification Service by setting the DefaultTemplateSid attribute. By doing so, the message body of the verifications created with the service will use by default the text defined in the template.
The default template SID<HJ> is a unique ID starting with the letters HJ. It is generated when the template is created.

A complete list of the available templates for the account can be obtained by querying the List Templates API.

The template that is going to be used in the verification will be defined following this order:

If a TemplateSid is received in the Create Verification request, the verification will use the text defined in the template identified with that Sid.
If a DefaultTemplateSid is set for the Service, the verification will use the text defined in the template identified with that Sid.
Otherwise, the text defined in the default template will be used.

Update a Service default template.
