In addition to sending messages through our services, you may also want to be able to receive messages sent to you by end users. To do so, you must first set up an endpoint with Vibes, which will let us know where to route the messages that come in from end users.

In the below article, we'll outline the technical requirements for your endpoint. Once the endpoint is created, please send the URL for your endpoint to your account manager to complete the process.

Setting up your endpoint

Originating Traffic

First, it’s important that your endpoint is compatible with the messages it will be receiving.

Callbacks can originate from several Vibes Data Center locations. Please make sure that your endpoint allows input from the following IPs:

US

• 35.155.139.143/32
• 52.32.61.199/32
• 35.161.244.84/32
• 18.205.120.48/32
• 52.22.43.57/32
• 18.232.9.131/32
• 54.245.204.57/32
• 54.148.156.236/32

EU

• 34.243.232.57/32
• 52.48.241.82/32
• 34.249.188.130/32
• 54.247.36.51/32
• 34.253.250.65/32
• 54.217.181.160/32

Your Endpoint Responses

When a call is made to your server, your server should respond to the Vibes API with an appropriate response code. A successfully processed message will return an HTTP Server Response of 2XX.

If the server responds with an HTTP Server Response of anything other than 2XX, then our system will assume that an error occurred and attempt to deliver the message again. This attempt will continue every five minutes, up to a maximum of five retries.

If the message continues to fail, the message will be moved into an error queue and our Operations staff will be alerted. At that point, our Operations staff will reach out to you and work to correct the issue. Once it’s resolved, any messages that are less than 24 hours old can be resent by our Operations staff.

🚧

Endpoint response required

Your endpoint must handle all message content delivered, even if it not usable by your endpoint. For example, if a mobile device texts in with a bad keyword, it is still your endpoint’s responsibility to log it and respond with a HTTP Response 200. If not, our system will continually retry the message until it is accepted.

Performance Considerations

To maintain a high-level of service, our callbacks have a relatively short timeout process of two seconds. We recommend minimizing any processing done synchronously on the callback and utilizing store and forward to avoid timeouts (and retries).

Receive an Incoming Message

Once your endpoint is set up, you can start receiving messages from end users. Note that our only capability is to provide the message from the end user to you; Vibes can’t verify keywords and won’t respond to the sender without a request from you.

Example Requests

Elements and Attributes of a Request

moMessage

This is the main wrapper element included in the delivery request.

source

The element identifying the source—or “sender”—of the message.

destination

This is the element that identifies the recipient of the message. For example, if the end user sent a text to number 12345, that information will be found here.

message

This element contains the body and content of the incoming message.

longMessageInfo

If the incoming message is longer than a standard text message, it may be split into multiple parts. If so, this element contains information about this long message.
