Configure CORS

Configuring Cross-Origin Resource Sharing (CORS) is only required if the API is being called from a browser app hosted on a different domain. For example, if your single-page JavaScript app is on example.com, but your API is hosted on api.example.com, you need to enable CORS.

• ASP.NET
• ASP.NET Core 2.x
• ASP.NET Core 3.x
• Go
• Node Express
• PHP
• Spring Boot

We suggest using the Cors Package for enabling cors. Once you have your express app instance, you can use cors:

var express = require('express')
var cors = require('cors')
var app = express()

app.use(cors())

For more details, refer to the Cors Package.
