Enrich new HubSpot contacts with Instagram creator stats

Build a deterministic code-based workflow that enriches every new HubSpot contact with Instagram creator data from Modash.

Trigger: an incoming webhook from HubSpot that fires when a new contact is created.

Steps, in order, each as its own discrete node:

1. Receive the HubSpot contact-created webhook payload and pull the new contact's ID out of it.

2. Use the HubSpot Get Contact operation to load the contact and read the Instagram handle off a custom property called instagram_handle (make the property name configurable).

3. If the instagram_handle property is empty, skip the Modash call and use the HubSpot Update Contact operation to set enrichment_status = no_handle on the contact, then stop.

4. If a handle is present, call the Modash Get Instagram Influencer Report operation with that handle as the userId.

5. Use HubSpot Update Contact to write these properties back to the contact: follower_count, engagement_rate, fake_follower_score, top_audience_country, top_audience_age_band, last_sponsored_brand, and enrichment_status = enriched.

6. If Modash returns a handle_not_found or other error response, instead set enrichment_status = handle_invalid on the contact and finish.

Keep this a straight node-based pipeline with structured input and output at every step. No LLM judgement is required; the only branching is the simple has-handle / no-handle / handle-invalid check.

Cost note for the reader: each successful enrichment costs one Modash credit, which acts as a natural per-contact rate limit.
