How it runs
Trigger: When an HTTP POST request hits its webhook URL (plus 1 other trigger).
- Compute signature (Crypto): hashes or encrypts values
- Staff thread replies only (Filter): keeps only the items that match a condition
- Signature valid? (If): checks a condition and branches into true / false
- Find customer (Data table): get (row)
- Config (Edit Fields (Set)): sets 4 fields: timezone, currency, acknowledgment…
- Send to LINE (HTTP Request): calls api.line.me (POST)
- Split events (Split Out): splits a list into separate items
- Sent? (If): checks a condition and branches into true / false
- Skip redelivered events (Remove Duplicates): removes duplicate items
- Mark as sent (Slack): add (reaction)
…plus 31 more steps. See the full node list below.
Services it uses
HTTP calls to: api.line.me
