We do offer a REST API, you can find all the information which includes everything from authentication, querying the API and creating webhooks below.
A few things to note:
Myphoner offers 2 levels of API keys, for information on the keys and where to find them check out this article.
If you do not have access to a developer you can work with one of our integration partners.
If there is a webhook or request you need that does not exist you can send a request to our support team and we'll do our best to create the needed function.
Our API does not have access to the data from the reports.
