Introduction

All calls to the iFax API should be made to https://api.ifaxapp.com/v1, which remains current with the latest minor updates. For most calls, you will need to pass in your API key as parameters. You can find your API key on the “Settings” page of your dashboard. In iFax, there are two types of credentials: Live and Test.

If you make an API call with a Live key, your balance will decrease if you perform operations that cost money (e.g. you send a fax). However, if you make calls with test keys, the iFax system will simulate faxes being sent or received and your balance will not be affected.

All iFax API responses are formatted in JSON. Need an XML response? Too bad. JSON is awesome! Click here to learn more about it.

HTTP Methods

Since our API is RESTful, each API call requires a specific HTTP method to indicate the type of operation to be performed. The method only has to be specified when interacting with the iFax API at the HTTP level, such as when using curl:

			
	            	curl -X POST https://api.ifaxapp.com/v1/customer/fax-send \
-H 'accessToken:API_KEY'

Method Simulation

Some HTTP clients don’t support all HTTP methods. In such cases, the POST method can be used, with the method for the API call passed in the _method parameter:

	              curl https://api.ifaxapp.com/v1/customer/fax-send
-F '_method=POST' \
-H 'accessToken:API_KEY'

Authentication

Most API calls require authentication. The client libraries have built-in authentication handling, which will automatically authenticate each request when properly initialized.

HTTP Authentication

HTTP authentication may be used simply by using the API key. For example:

	              		cURL
curl 'https://api.ifaxapp.com/v1/customer/fax-send' \
-H 'accessToken:API_KEY'

Formats

By default, all API calls return a JSON response. Click here to learn more about it.

Objects

Fax Object

The fax object is a JSON object returned by the iFax API and represents a fax job in the system. Its properties are described in the table below.

Name	Description
jobId	A unique ID generated for each fax sent through the API. This can be used to retrieve the fax’s status, cancel a fax or resend a failed fax.
fromNumber	The number (in E.164 format) the fax was sent from.
toNumber	The number (in E.164 format) that received the fax.
faxCallLength	The total time spent (in seconds) from when the API call was made until the fax processing ended.
faxCallStart	A timestamp (in Unix time) indicating when the initial API call was made.
faxCallEnd	A timestamp (in Unix time) indicating when the fax processing ended.
faxTotalPages	The total number of pages in the fax being sent.
faxTransferredPages	The total number of pages in the fax that were successfully sent and received by the recipient.
faxStatus	The status of the fax. Can be any of the following: ‘sending’, ‘delivered’, ‘canceled’, or ‘failed’. Click here for more information.
message	A detailed description of the fax status or error, if any.
code	A numeric code that indicates a more accurate representation of the fax status or error, if any.

Example Fax Object

	          		{
	          	   		"jobId": 12345,
	          	   		"fromNumber": "+441224515014",
	          	   		"toNumber": "+15065001844",
	          	   		"faxCallLength": 173,
	          	   		"faxCallStart": 1610966603 (UTC timestamp),
	          	   		"faxCallEnd": 1610966723 (UTC timestamp),
	          	   		"faxTotalPages": 20,
	          	   		"faxTransferredPages": 20,
	          	   		"faxStatus": "delivered",
	          	   		"message": "NORMAL_CLEARING",
	          	   		"code": 0
	          	   	}

Webhooks

Webhooks allow iFax to update you in real-time about the status of your faxes. Webhooks are triggered by events such as the completion of a fax, and transmit information about the state of that fax to you via HTTP(S).

Specifying Webhook URLs

The first thing we need to send you a webhook is a destination URL. This should be a valid URI with a http, https scheme that points to a destination that you control. An example of a valid webhook URL is https://www.example.com/ifax_webhook

For sent and received faxes, you can set global webhook URLs on your webhook settings page. These apply to all faxes on your iFax Acount.

Specifying a Webhook Version

Coming Soon

Enabling Inflight Webhooks

Currently, iFax supports two categories of webhooks: postflight and inflight. Postflight webhooks are triggered when a fax completes, regardless of success. Inflight webhooks are triggered by events during the transmission of a fax, such as the transfer of individual pages.

Inflight webhooks are disabled by default, but can be enabled on the webhook settings page.

Retries

If a webhook fails, We will automatically retry up to 5 times. There will be a backoff before each retry, which increases as follows:

Retry No.	Backoff
1	5 minutes
2	10 minutes
3	20 minutes
4	30 minutes
5	60 minutes

Fax Statuses

Will receive the following possible status in API responses

Name	Description
sending	The system is currently sending the fax and communicating with the recipient machine.
delivered	The fax has been successfully sent and received by the recipient machine.
canceled	The fax has been cancelled successfully.
failed	The system has failed to send the fax successfully. Refer to the error codes here to know more about the specific error.

Receive fax callback

When a fax is received, iFax will post information about the fax (including any metadata received from PhaxCodes) along with a PDF of the fax to your receive fax callback URL, if one is available. You can set up a receive callback URL on the callbacks page in the web console.

The callback HTTP request is a multipart POST and should be processed like a form submission. The PDF of the received fax will be contained in a file upload part of the request named ‘filename’.

Retries

If a callback fails, we will automatically retry the callback up to 16 times. There will be a backoff before each retry, which increases as follows:

Retry No.	Backoff
1	5 minutes
2	10 minutes
3	20 minutes
4	30 minutes
5	60 minutes

Billing

We thought it would be useful to let you know how our billing process works at the different stages of your API calls, so you can have more insight as to why and when your funds will be depleted.

Sending Faxes

When you make an API call to send a fax, we check your balance. If it’s too low for the price of the fax, the call results in an error and we stop the process. Otherwise, we queue the fax for sending.
Right before the fax is actually sent over the wire, we again check your balance. If it’s too low for the price of the fax, the call results in an error and we stop the process. Once your balance is high enough, we deduct the price of the fax (factoring in all of the recipients you’re sending to).
When the fax transmission process has ended, we check to see if any recipients did not receive the fax successfully (e.g. line busy, bad connection, etc.). We then credit your account the price of the fax for each recipient that encountered an error.
