This is a powerful automation — but like all powerful tools, it comes with responsibility.
⚠️ Disclaimer: Use with Care
Each application costs credits. If you set up this action without rules, you risk applying on everything → draining your credits fast.
There is no auto-refund for wrong or irrelevant auto-applies.
Misusing this action could also create a bad experience for buyers, which hurts your chances of winning projects.
👉 Always combine this action with Filters and/or AI decision trees before auto-applying.
🔑 Required Field: Opportunity ID
To apply on a project, the action needs the Opportunity ID.
This ID is provided in the trigger step (e.g., New Opportunity Received).
You must map the field
opportunity.idfrom the trigger into the Apply on Opportunity action.Without this ID, the action cannot execute.
Example mapping:
Trigger: New Opportunity Received →
opportunity.id = 123456789Action: Apply on Opportunity → Opportunity ID =
{{opportunity.id}}
🛡️ Best Practices
Use Zapier Filters for Hard Rules
Example filters:Country = France
Employees ≥ 40
Budget ≥ €10k
Language includes English OR French
Use Paths for OR Logic
Example branches:Path A: Budget > €10k AND Employees > 40
Path B: Budget missing AND Employees > 100
Add AI for Smart Decisions
Use OpenAI to check project description vs your agency expertise.
Only continue if the AI says TRUE (Apply).
Prompt example:
“Answer only TRUE or FALSE. TRUE if the project clearly matches my agency profile. Otherwise FALSE.”
⚠️ Note: AI tokens cost money. If you receive hundreds of opportunities per week, the cost can add up quickly. For cheaper solutions → rely on Paths & Filters as much as possible, and reserve AI for cases where text interpretation is really needed.
