If you use PHP, you can install our library - Sendios-SDK.

Before sending emails, you need to do the following:

  1. Configure Sender and Tracking Domains;
  2. Configure SPF/DKIM records according to Sender Domain Settings;
  3. Create a project;
  4. Create a template;
  5. Create a transactional email.

All API points work asynchronously, which means if you get a 200 OK response, we received your request, and it was processed and validated. To find out the status of email sending go to the admin panel to the User profile section or use webhooks.

Authorization is required to make requests to the server. The following steps should be performed:

  1. Request clientId and API key at Customer Success Manager;
  2. Encode the string {clientId}:{api_key} in base64;
  3. Enter the received coded string into the authorization header.
ParamsDescription
clientIdClient identifier
api_keyAPI key
curl -X GET https://api.sendios.io/v1/something-else \
-u {clientId}:{api_key}

If you use our Sendios SDK library, then you need to request clientId and SDK key at Customer Success Manager.

🚧

Currently, only the PHP SDK is supported, and other programming languages are not available for use.

You can find out about the status of the system on the website https://status.sendios.io/: in case of incidents or unavailability of the system, we notify about problems and publish actual information. More options for monitoring can be found in the article Sendios Monitoring.
