If enabled, this plugin terminates the ongoing request to that particular URI and initiates a new request to the aws lambda gateway uri (the new upstream) on behalf of the client with the suitable authorization details set by the users, request headers, request body, params ( all these three components are passed from the original request ) and returns the response body, status code and the headers back to the original client that has invoked the request to the APISIX agent. +At present, the plugin supports authorization via aws api key and aws IAM Secrets. + +## Attributes + +| Name | Type | Requirement | Default | Valid | Description | +| ----------- | ------ | ----------- | ------- | ----- | ------------------------------------------------------------ | +| function_uri | string | required | | | The aws api gateway endpoint which triggers the lambda serverless function code. | +| authorization | object | optional | | | Authorization credentials to access the cloud function. | +| authorization.apikey | string | optional | | | Field inside _authorization_. The generate API Key to authorize requests to that endpoint of the aws gateway. | | +| authorization.iam | object | optional | | | Field inside _authorization_.

Calling the APISIX route uri will make an invocation to the lambda function uri (the new upstream). We are assuming your cloud function is already up and running. + +```shell +# enable aws lambda for a route via api key authorization +curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' +{ + "plugins": { + "aws-lambda": { + "function_uri": "https://x9w6z07gb9.execute-api.us-east-1.amazonaws.com/default/test-apisix", + "authorization": { + "apikey": "<Generated API Key from aws console>", + }, + "ssl_verify":false + } + }, + "uri": "/aws" +}' +``` + +Now any requests (HTTP/1.1, HTTPS, HTTP2) to URI `/aws` will trigger an HTTP invocation to the aforesaid function URI and response body along with the response headers and response code will be proxied back to the client.
