Is it possible to use a static template ID to send envelopes in DocuSign using PHP?

My requirement is once admin set template and their variable to send that template to recipient to sign the envelop. Currently I have follow to create template each time using https://developers.docusign.com/docs/esign-rest-api/how-to/create-template/

Conclusion : How can I avoid to create template and send envelop using my static template id

I want to avoid create template each time

https://developers.docusign.com/docs/esign-rest-api/how-to/request-signature-template-remote/ shows what you are asking and here is the PHP code which can also be found here - https://github.com/docusign/code-examples-php/blob/master/src/Services/Examples/eSignature/UseTemplateService.php

private function make_envelope($args)
{
# Create the envelope definition with the template_id
$envelope_definition = new \DocuSign\eSign\Model\EnvelopeDefinition([
'status' => 'sent', 'template_id' => $args['template_id']
]);
# Create the template role elements to connect the signer and cc recipients
# to the template
$signer = new \DocuSign\eSign\Model\TemplateRole([
'email' => $args['signer_email'], 'name' => $args['signer_name'],
'role_name' => 'signer'
]);
# Create a cc template role.
$cc = new \DocuSign\eSign\Model\TemplateRole([
'email' => $args['cc_email'], 'name' => $args['cc_name'],
'role_name' => 'cc'
]);
# Add the TemplateRole objects to the envelope object
$envelope_definition->setTemplateRoles([$signer, $cc]);
return $envelope_definition;
}
