Docs Glossary API


What Is an API?

An API is way for 2 systems to communicate and exchange data.

In this context, ‘systems’ can mean any combination of websites, apps, software, or servers.

Our API lets you connect your website or app to SendLayer. You can then use the API to send emails or retrieve information. For example, you can find out whether your emails have been delivered successfully and whether the recipients have opened them.

What Does API Stand For?

API stands for application programming interface. APIs help servers and software communicate with each other to achieve certain tasks – like sending emails.

What Is an Endpoint?

An endpoint is the ‘connection point’ for the API.

An email API will usually have several endpoints, including an endpoint to send email and a different endpoint to retrieve the email log afterward.

How Can I Send Email With an API?

You can send emails through an API by connecting your application to SendLayer. For testing, you can use an API platform like Postman to send emails through the SendLayer API.

That’s it! Now you know what an API is.
