Go client library for Retool API

The library code is generated from OpenAPI spec using OpenAPI Generator.

Install

Install OpenAPI Generator launcher script

brew install mvn

mkdir -p ~/bin/openapitools
curl https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/bin/utils/openapi-generator-cli.sh > ~/bin/openapitools/openapi-generator-cli
chmod u+x ~/bin/openapitools/openapi-generator-cli
export PATH=$PATH:~/bin/openapitools/

You'd want to update your shell file (.bashrc or equivalent) so that it adds ~/bin/openapitools/ to your PATH .

NOTE: You might have to install newer version of JDK that we have by default on our laptops. I downloaded one from https://adoptium.net/ and set my JAVA_HOME env var to /Library/Java/JavaVirtualMachines/temurin-21.jdk/Contents/Home

Prepare the OpenAPI spec

If you want to update the client code to cover recent changes in the Retool API, you'd need to update openAPISpec.json file first:

• download new spec from e.g. https://api.retool.com/api/v2/spec
• format it so that it's human-readable ("Format Document" command in VSCode would do)
• manually make sure that every tags element has only one value.

Why do we have to manually edit tags? Otherwise OpenAPI Generator will generate the same request/response structure for every tag value and you'll get compile errors. Leave the tag that corresponds to the top-level element in the endpoint path. So, if the tags are ["Users", "User Attributes"] for /users/{userId}/user_attributes/{attributeName}, you should only leave ["Users"]. See https://github.com/OpenAPITools/openapi-generator/issues/741 for more details and potential alternatives that we may explore in the future.

NOTE: To make the client work with our API, I had to manually update openAPISpec.json in quite a few places. So, I'd recommend manually copying the fragment of the spec that you need into the file instead of trying to replace the file completely.

Generate client library code

Just run go generate in this folder. All generated code lives in the api folder. Command line parameters for openapi-generator invocation are controlled via generate.go file.

Test client library

There's a simple executable in client folder that makes an API request to localhost:3000 and prints out the response. You can run it as follows:

RETOOL_ACCESS_TOKEN=<your API token generated on localhost:3000> go run client/main.go
