How to use Request Lab
- Open the template in Screenshot Studio. “Use this template” opens a new-project dialog in your browser; nothing is saved until you choose Create.
- Upload and map your app screenshots. Slots are named Collections, Request editor, Headers, Response, History.
- Edit the headlines and supporting descriptions. Click any text on the canvas or use the copy table for every language.
- Apply your colours, fonts and target sizes. Brand kits and per-size adjustments keep the master layout intact.
- Preview, validate and export. Validation flags empty slots, overflowing text and missing fonts before the PNG export.
Advice for this template
- Use a collections screen for slide one, a request editor screen for slide two, a headers screen for slide three, then response and history screens for slides four and five.
- Use legible editor captures and keep code examples large enough to read in the final artwork.
Questions
- Which app screens work best in this template?
- In order: collections, request editor, headers, response and history. Each slide has a named screenshot slot so captures map by position.
- Can I replace the device frame?
- Yes. Each screenshot slot can switch between the generic drawn frame styles (including frameless cards). Realistic manufacturer device artwork is not bundled.
- Can I change the gradient colors?
- Yes. The background is an ordinary editable gradient; the template also offers a matching solid colour and an alternate light/dark treatment.
- Can I use this design for both platforms?
- Yes. Projects can target App Store and Google Play sizes together. The master layout is 1320 × 2868; other sizes are resized proportionally, and you can adjust any size individually.
- Which parts remain editable?
- Every headline and description, screenshot slot, background and SVG decoration is an ordinary named layer you can edit, recolour, move, hide or delete.
