Five steps to successful SMS dispatch via our API
Follow the simple instruction to start sending SMS via our Messaging API within a very short time.
Set up a free test account
To use our Messaging API for sending SMS, you need to create an API token using a test account. Setting up a test account is a quick and easy process that can be completed in a few steps.
Verify a mobile phone number to send test messages
Verify your phone number via the pop-up when you log in for the first time.
During the test period, you can only send messages to the mobile phone number you have verified. You will receive 50 SMS free of charge and can optionally extend this quota. Your mobile phone number will not be passed on to third parties and will not be used for advertising purposes.
Set up two-factor authentication (2FA) to enable the allocation of an API token.
Only accounts with activated 2FA are authorised to create API tokens.
Create API token
Log in to the messaging portal. Select API administration from the menu on the left-hand side. Click on the API access data. You see API Tokens at the top right. Here you can Create new token.
Sending SMS via HTTP GET
Open your programming or test environment. We are using the Postman tool here. In this example, we use the authentication method via API token and only use absolutely necessary parameters. Use the endpoint https://api.linkmobility.eu/rest/smsmessaging/simple, define your access_token, messageContent and enter your verified mobile phone number as the value of the recipientAddressList parameter.
Read the documentation for REST Messaging API and find out more about authentication and the methods of the SMS interface.
The following parameters must be included in the request:
| Query Parameter | Example | Note |
|---|---|---|
| access_token | f2664813-05c1-4117-ac42-5f0a8ac2ebb7 | Generate your own API token in the messaging portal |
| recipientAddressList | 436609876543 | Your verified mobile phone number |
| messageContent | Hello%20World%21 | UTF-8 URL encoded text |
The message is not automatically encoded. You can use a tool such as urlencoder for UTF-8 encoding.
Trigger the GET request and check the returned status code.
If the transmission was successful, you should receive the following response:
statusCode=2000&statusMessage=OK&transferId=0062053f400024d8acae&smsCount=1
If the status code 2000 is returned, the transmission of the SMS via the LINK | Messaging API was successful.
Receive SMS on your mobile device
If everything works, you will receive your first SMS within a very short time
Congratulations and good luck with the development of your business messaging solution with our Messaging API!
