Develop three scripts on PHP integration with AMO CRM (deals, tasks)

For the current version of the AMO CRM API, develop three scripts on PHP:

There is a phone number at the entrance. You want to make a software request in AMO CRM in order to get in the script the transaction code (a list of transactions, if several), to which the specified phone number is tied. For a transaction/to-list transaction, the software request to add to the transaction in the AMO CRM information about the phone call external link to the call recording file. Create a new task in AMO CRM with call information from a phone not tied to a transaction (in case the phone is not tied to any transaction in p.1).
