Is there anyway to send Firebase Access Token Key and SendId in Application Runtime?

Because of our company policy, we won't give access token key and send id to anyone including me. The only way we can get it from API call in application runtime and we set those value in runtime. I go through the zendesk documentation and I couldn't find a way to set firebase access token key and send id programmatically. Is someone know how to setup access token key and send id programmatically, please let me know?
