I’m having trouble setting up proper OAuth 1.0 authentication when making calls to Twitter’s API through Zapier’s webhook feature.
When I use tools like Postman, the authentication works perfectly. I just need to provide my consumer key, consumer secret, access token, and token secret. Then I select HMAC-SHA1 as the signature method and enable the option to encode the OAuth signature. The REST client handles all the signature generation automatically.
However, in Zapier I need to manually generate this OAuth signature somehow. I’ve been trying to figure out how to compute this signature using Zapier’s available Python or JavaScript code modules, but I’m stuck.
Has anyone successfully implemented OAuth 1.0 signature generation within Zapier? If there’s a working solution, it would unlock many integration possibilities with Twitter’s API.
totally feel u! i had the same issues with zapier too. tried Pipedream and it was so much easier - they do all the oauth signing stuff for ya. def worth a shot!
Got this working using JavaScript in Zapier’s Code step to build the OAuth 1.0 signature directly. You need to concat the HTTP method, encoded URL, and encoded parameters into a base string, then generate the HMAC-SHA1 signature with the crypto module. Twitter’s super strict about encoding and parameter ordering - that’s the tricky bit. I had to write a separate function for percent encoding that follows RFC 3986 exactly. Add the signature to your Authorization header with the other OAuth params. Took some debugging to nail the parameter concatenation, but it’s been rock solid for months once I got it right.
Hit this same issue last year. Built a workaround with Zapier webhooks and a simple middleware service. Don’t try generating OAuth signatures in Zapier - it’s a pain. I made a small Node.js service that takes the Twitter API params from Zapier, handles OAuth 1.0 signing server-side, then sends the authenticated request to Twitter. It passes the response back to Zapier without any issues. Saved me tons of debugging time and works great across different Twitter endpoints. You can deploy something like this on Heroku or Vercel pretty fast if you don’t want to deal with OAuth signing in Zapier’s limited environment.
