How to Build an Approval Workflow App Without Code
Design an approval app around request states, approver roles, thresholds, evidence, exceptions and audit history before you start building.
Model the decision, not the form
The form is only intake. The workflow begins when a submitted request becomes eligible for a decision. Define the statuses first: Draft, Submitted, In Review, Approved, Rejected, Returned and Cancelled are common, but your process may need fewer.
Assign authority explicitly
Write rules such as “Department managers may approve requests up to $5,000; finance must approve above that threshold.” Avoid vague requirements like “send to the right person.” The builder needs deterministic logic or a clearly defined manual routing step.
Prototype this in Base44
If you have already mapped the users, records and states, Base44 can be used to turn that specification into a working prototype.
Start building with Base44 →Capture the evidence behind the decision
- Requester and department
- Amount or risk level
- Business justification
- Attachments
- Approver identity
- Decision timestamp
- Decision note or rejection reason
Design the exception path before launch
What happens if the approver is unavailable, the request changes after approval, or finance sends it back? A workflow that only supports the happy path forces the team back into email as soon as reality arrives.
Prototype one approval chain
Build the simplest real scenario and test it with the people who actually approve. Confirm access boundaries and notifications before adding dashboards or complex branching.
Ready to test the fit?
Open Base44 with a concrete workflow in mind and judge it against the requirements in this guide rather than against a generic demo.

Product facts can change. OpsToolLab checks time-sensitive claims against first-party sources and dates pages when reviewed.
Keep researching
Minimum viable approval specification
Before opening a builder, write one example request with realistic data and walk it through every state. Name the exact person or role allowed to move it, what validation is required, and which side effects occur. Include one returned request and one cancelled request. If the group cannot agree on those examples, the blocker is process design rather than software.
After building, test with separate accounts rather than switching roles in your head. Confirm that the requester cannot approve their own request unless that is intentionally allowed, and that the audit trail explains the final decision.
