One of the most common questions regarding the InterFAX free developer account is “how can I test sending faxes to other numbers to see different responses?”. The answer is the InterFAX Simulator.
InterFAX now enables developers to submit faxes to a list of specific numbers and simulate the behavior (success or failure) of the fax delivery.
The test numbers provided by InterFAX are dummy numbers which means we won’t make any phone calls and nothing will be printed on the other side. However, everything else within the InterFAX processing will take place as per the live process.
You can use the InterFAX Simulator to help develop and enhance your integration. Here are a few ideas:
- Simulate a behavior of a fax ending up with a busy signal. What will your system do next?
- Simulate a behavior of a fax call that results in no answer. See how the callback is sent to you and what information is sent back (read more about our callback system).
- Simulate sending a batch of faxes to multiple recipients - where some of the fax calls are successful and some fail - and poll through the faxes to retrieve their individual status (read more about polling faxes).
How can I start using the InterFAX Simulator?
Once you are a registered developer; when sending a fax, simply submit the fax to a number format as +999-9999-[result code]. The [result code] should be replaced with the result code that you would like to simulate in InterFAX (the result code should be one of InterFAX’s fax transmission status codes).
Please note that the [result code] cannot be longer than 4 digits.
- In order to experience a fax that results in success, submit the fax to number +999-9999-0.
- In order to experience a fax that results in failure due to a busy signal, submit the fax to number +999-9999-6017
