Which API for Go lang should I use?
Discover the advantages and disadvantages of each of our APIs. Find out which API is best for your Software in Go lang.
This API allows you to connect to us from Go lang to send requests via HTTP GET requests. This request sends the parameters in the same URL as the request.
- HTTP GET is extremely simple to implement
- Information is sent unencrypted (passwords could be extracted from logs or cache)
- Maximum request of ~4000 characters
The POST request API allows you to connect to our API from Go lang by sending request parameters via HTTP POST parameters. The information is sent independently of the URL.
- HTTP POST is simple to implement
- Information is sent encrypted
- There is no limit on the size of the request
- Medium security
The basic authentication API allows the use of GET and POST requests in Go lang with an additional security layer, since in this case the username and password are sent in the header of the request.
- Basic authentication is easy to implement
- Access data is sent encrypted
- The size limit depends on the use of GET or POST
- Medium security
SOAP allows you to send requests in XML format with Go lang, SOAP adds an extra layer of security to API requests.
- SOAP integration is more complex
- Information is sent encrypted
- There is no limit on the size of the request
- Medium / High security
Our JSON API allows you to send requests in JSON format with Go lang, in addition this API adds the oAuth 2.0 protocol in the authentication that allows you to add an additional layer of security.
- JSON oAuth 2.0 integration is more complex
- Information is sent encrypted
- There is no limit on the size of the request
- High security
