About apis.pk

apis.pk is a developer reference for Pakistani and global developers: guides to WhatsApp and SMS APIs, JSON, cURL and HTTP, webhooks and authentication, plus developer tools that run entirely in your browser.

Ownership disclosure

apis.pk and our sister site Free SMS Gateway are run by the same team that runs WaSMS, a service for sending SMS and WhatsApp messages. We tell you this so you can weigh what we write accordingly.

• WaSMS is never in our navigation, footer, banners or buttons.
• When a guide answers “where do I get this?”, WaSMS may appear as one option among others, with a note that it is run by the same team as this site.
• Our tools work the same for everyone and never send your input to WaSMS or anyone else.

No sign-up, no selling

You don't need an account for anything here, and we don't sell anything on this site. The tools run in your browser — see our privacy policy for the details.
