The Goal: Gathering Additional Partner Data

Your sign-up form is your first opportunity to qualify a partner. Studies show that collecting just three to five non-essential fields can boost the quality of your applicants by up to 40% because it filters out low-effort sign-ups. This article shows you how to use the Onboarding section to control exactly what data you gather. By customizing your fields, you ensure every partner provides the strategic information you need, turning simple sign-ups into highly qualified assets.

How to Manage Sign-up Fields

The Onboarding section (found under Settings -> Onboarding) lets you control both the default fields and add your own custom questions.

Why Customize Fields in the Onboarding Section?

The Onboarding section lets you collect specific, extra data beyond the basic name and email that Tapfiliate gathers by default. This information helps you:

Better Check Partners
Learn about their promotion methods, social media following, or audience size.
Segment Affiliates
Sort partners into groups based on the information they provide.

Custom Fields: Adding Your Own Questions

You can ask for specific details like social media links, audience size, or a preferred coupon code. Standard sign-up forms capture basic information, but Custom Fields allow you to gather specific, high-value data essential for managing a professional partnership program. This powerful feature helps you vet potential partners, understand their audience reach, and automatically categorize them for targeted communication and reward structures. The table below details how to configure these fields.

Setting	Purpose	Available Field Types	Validation Explanation & Example
Delete	Click the trash icon to permanently remove the custom field from your sign-up form and the system.	-	-
Field Name	The label the affiliate sees (e.g., Phone number).	-	-
Field Type	Defines the format of the answer: Text lets the affiliate type their answer freely. Multiple choice makes the affiliate choose the answer from a dropdown list.	Text Multiple choice	Example (Text): “Your Instagram Handle” Example (Multiple choice): “How did you hear about us?”
Required	If ON, the affiliate must complete the field to finish sign-up.	-	-
Validate as	Sets rules to ensure the data format is correct.	No validation Email Regex (advanced)	Email: Ensures the input is a valid email address (e.g., must contain @ and .com). Regex: Use for specific, complex formats (e.g., forcing a 7-digit coupon code).
Description	Adds a small note or hint directly beneath the field for the affiliate.	-	Example: “Please provide your primary channel URL.”

Important: Never use this feature to collect sensitive data, such as Social Security Numbers (SSN).

IMPORTANT: Plan Requirement

The Custom Sign-up Fields feature is available only to users on the Scale and Enterprise plans.

How to Manage Default Onboarding Fields

In the Onboarding section, you can control the visibility and importance of the default fields Tapfiliate provides (such as Website, Address, and Company details).

Understanding Visibility and Requirement

The standard toggle (On/Off) and the Hide field checkbox work together to manage the user experience:

Setting Combination	Field Visibility	Field Requirement	Purpose
Toggle is ON	Shown to the affiliate.	Required for the affiliate to complete sign-up.	Use this for essential data, like the affiliate’s Country or Payout method.
Toggle is OFF	Shown to the affiliate.	Optional (not required) for the affiliate to complete sign-up.	Use this for important but non-critical data, like the Company Description or Address.
Toggle is OFF AND “Hide field” is checked	Hidden from the affiliate entirely.	Not applicable.	Use this if you do not need this information at all during sign-up.
Toggle is ON AND “Hide field” is checked	This combination is not possible.	The system prevents this conflict.	A required field cannot be hidden.

In simple terms:

Toggle ON (Required): The field is visible and the affiliate must fill it out.
Toggle OFF (Optional): The field is visible, but the affiliate may skip it.
Toggle OFF + Hide field: The field is completely hidden from the sign-up form.

The fields you created will appear in the affiliate’s portal during their onboarding process.
