# Verae Time for Zapier — user guide How to go from **zero account** to **registering SHA-256 hashes**, **looking them up on the central Verae chain**, and **finding hashes that were only sealed as part of a bulk Merkle summary** on external tree-node archives. This is the customer-facing guide (signup → Zaps). Developers: see [zapier-docs-master](https://git.georgelambert.org/marchon/zapier-docs-master) and the simulator at [verae-zapier-simulator](https://git.georgelambert.org/marchon/verae-zapier-simulator). **Live catalog:** https://zapier.georgelambert.org/ **Clone:** `ssh://git@git.georgelambert.org:2223/marchon/zapier-user-docs.git` ## Contents 1.

[Security: what Zapier never sees](12-security.md) ## Try it without going live The [interface simulator](https://git.georgelambert.org/marchon/verae-zapier-simulator) is a Zapier-like form plus a trace console. Run **Batch Merkle**, copy a leaf SHA-256, then **Find Timestamp by SHA256** (miss) vs **Find Hash (tree nodes)** (proof).
