Lovable API: Build with URL

Example workflows

Starting points built from this record, not transcripts of a run. Each prompt is written the way it should be sent, as one paragraph, and each is worth editing before you send it.

1. 01

   Stand it up from scratch

   You have read the record and want Lovable API: Build with URL working in a real project rather than a sandbox.

   Set up Lovable API: Build with URL in this project — kick off a Lovable build from a URL with prefilled context. It is still in beta, so build the smallest version that proves it works, tell me exactly what you changed, and flag anything I have to switch on myself.

   Expected outcome

   A working setup, a plain list of what changed, and a short list of anything left for you to switch on. Check that list before assuming it is done.

2. 02

   Branded 'Build in Lovable' buttons

   The record lists this as one of the jobs Lovable API: Build with URL is meant for, so it is a fair first test of whether it fits your app.

   In this project, use Lovable API: Build with URL for branded 'Build in Lovable' buttons. Build the smallest version that a real user could complete end to end, keep the change scoped to that path, and tell me how to test it myself.

   Expected outcome

   One complete path a user can walk, the files and settings that changed, and the steps to test it. Walk it yourself before you ship it.

3. 03

   Review it before you publish

   Lovable API: Build with URL is wired in and you are about to put it in front of people. This is the pass that catches the half-configured version.

   Review how this project uses Lovable API: Build with URL before I publish. Check prefilled prompt + parameters and lovable Link Generator helper, list anything that is missing, misconfigured, or only half wired, fix what is safe to fix, and tell me what you left alone and why.

   Expected outcome

   A findings list split into what was fixed and what was left, with a reason for each. Anything left alone is yours to decide on.

4. 04

   Curated template launchers

   A second job the record lists for Lovable API: Build with URL, useful once the first path works.

   Extend this project so Lovable API: Build with URL also covers curated template launchers. Reuse what is already wired rather than adding a parallel setup, and tell me what you reused and what is new.

   Expected outcome

   A second path built on the same setup, plus a note on what was shared and what was added.
