Question 1

How do I authenticate Farcaster casts using Neynar's SIWN?

Accepted Answer

Neynar's Smart Contract Signer (SIWN) handles wallet authentication via Ethereum signatures, allowing you to sign cast requests securely without exposing private keys.

Question 2

Can I write cast metadata to Google Sheets automatically?

Accepted Answer

Yes—B3OS maps each cast field (text, image URLs, reactions) to designated columns, updating the sheet in real time whenever a new cast arrives.

Question 3

Is there a rate limit when syncing casts to Sheets?

Accepted Answer

The integration respects Farcaster's API rate limits and Google Sheets' quotas, queuing excess casts and processing them asynchronously to avoid throttling.

Question 4

Do I need coding skills to set up the integration?

Accepted Answer

No—B3OS provides a no‑code UI where you select the trigger (new cast) and destination (Google Sheet), then configure mapping fields with simple dropdowns.
