How to build your affiliate registration form

The registration form is the first thing a potential affiliate sees from your program. It should convince good partners that joining is worth their time, and collect what you need to vet them. Every store starts with a working default form, so you can launch right away and refine it once applications arrive.

Quick steps

1. In BLOOP Refer & Aff → Affiliate program, open the Branding tab and click Customize on Affiliate registration:

   

2. In the Form fields tab, review the three default fields, then click Add field to ask for more.

3. Pick a Field type.

4. Enter a Label.

5. Turn on Required if you need the answer to approve or contact the applicant.

6. Click Save in the bar at the top of the page.

7. In the blue banner of the Form fields tab, click Open app block:

   

8. Shopify opens the theme editor for your live theme with the Aff registration form block added. Move it where you want it, usually on its own page, and click Save.

The form doesn’t appear on your store until you add the block, so there is no link to share before then. The block is only available while the affiliate program is turned on. If the banner shows Update and View old version instead of Open app block, your form still uses the old version: click Update first.

Keep the form short

Every field costs the applicant time, so each one should answer a question you’ll use: what decision does this help me make?

If you’re tempted to ask for…	Do this instead	Why
Phone numbers, addresses, tax details or essays	Let affiliates add payout details in their portal after approval. You choose which methods they see in Payment settings	Good creators drop off, and you don’t need these details to approve anyone
Only an email address	Add one screening question	An email-only form admits bots and people with no relevant audience

For most stores, the right form is a name, an email, one screening question and a terms agreement.

Default fields

Three fields are required: first name, last name and email. You can rename their labels or change the placeholder text, but you can’t make them optional or delete them.

Field types

Field type	What it collects	Use it for
Text field	One line of free text	A name, social handle or website, when the answer is short
Radio button	One option from a list	A single category, such as niche, platform or audience size
Multiple-checkbox	Several options from a list	Channels or product lines
File upload	One file: JPEG or PNG, up to 5 MB each	A screenshot of a profile or audience stats
Terms agreement	One checkbox linked to your terms	Explicit agreement to your program terms

Builder rules

• Unique labels: labels must be unique, and case doesn’t matter. If you see “Label is duplicated”, rename one of the fields.
• Required settings: a field’s label and options can’t be blank. Fill them in before you save.
• One Terms agreement: a form has at most one. Once you add it, other fields can’t use that type.
• Multiple-checkbox: always optional. If you need the answer, use a Radio button instead.

Field settings

Field type	Setting	Notes
Text field	Placeholder	A hint about what to type
Radio button, Multiple-checkbox	Options	Add, edit or remove options
File upload	Placeholder	For example, “Choose a file”
Terms agreement	Term name and term link	Put {terms} in the label where the link should appear, for example I agree to the {terms}. Without {terms}, the field won’t save

Public uploads have a daily limit per store. It stops abuse and doesn’t affect normal sign-up volume. If the limit is reached, applicants can’t attach files until it resets. Keep the File upload field optional so sign-ups still go through.

Turn screening questions into choices

Free text is flexible, but you can’t sort it. Choices let you compare applicants in seconds. Asked “What’s your audience size?”, free text gives you “A lot” or “10k ish”, while Radio button bands give you Under 1k, 1k–10k, 10k–50k or 50k+.

Example: a lean screening form

Say you run a skincare store and want creators with a real audience. This form recruits and screens at the same time:

1. First name (default, required)
2. Last name (default, required)
3. Email (default, required)
4. Where do you post? Multiple-checkbox with the options Instagram, TikTok, YouTube, Blog and Other. Optional. It shows the channel mix without blocking sign-up.
5. Audience size. Radio button, required, with the bands Under 1k, 1k–10k, 10k–50k and 50k+.
6. Screenshot of your audience stats. File upload, optional. Serious creators can prove their reach without forcing casual applicants to do the same.
7. Terms agreement (required), with the label I agree to the {terms} and the term name “Affiliate Program Terms”, linked to your policy page.

That’s seven fields: five required and two optional. Each one earns its place. See Managing affiliates to see how these answers show up in review.

Page content

Beyond the fields, you control the wording around the form:

Part	What to write
Header	A title and sub-title that introduce the program
Form labels	The submit button text, the “Already have an account?” line and the sign-in link
Benefits and How it works	Bulleted lists that sell the program. Lead with the commission. A form with no benefits and no commission number gives a prospect no reason to join
Thank-you page	The title, body and button shown after a successful submission

Use dynamic variables so the page shows your real numbers. Supported variables include {{store_name}}, {{email}}, {{cookies}} and {{campaign_amount}}. For example, “Earn a {{campaign_amount}} commission on every sale.”

If the page feels crowded, change Display in the Settings tab:

Display	What it hides
Only form	The header and the information panel (benefits and How it works)
Title with form sections	The information panel. The header stays

Styling the form

Match the style to your store theme, so the application page feels like part of your brand. For the portal affiliates see after signup, read Portal style.

Style group	What it changes
General	Button color, font family, heading and content font sizes, Display, and square or rounded borders
Header style	Title and sub-title colors and sizes
Information style	Background and text colors for the benefits panel. It shows when Display includes the information section
Form style	Background, text and submit button colors for the form

Protecting the form from bots

Bloop filters the most common bot sign-ups for you:

Protection	What it does	What you do
Hidden trap field	Blocks sign-ups that fill in an invisible field. No affiliate is created	Nothing
Rate limits	Refuses repeat submissions from one visitor in a short time. An unusual burst of sign-ups is held as Pending with no email, even when approval is automatic	After a launch, check the Affiliates tab for unexpected Pending applicants
Own fields only	The form saves only its own fields. Status, campaign, coupon and payment details never come from the form	Nothing. Assign a campaign when you approve, and affiliates add payment details in their portal

If bots still get through, turn on Enable CAPTCHA at the top of the Form fields tab. CAPTCHA is a quick check that tells people from bots. Applicants complete it (Cloudflare Turnstile) before they can submit. It’s off by default.

Some ad and content blockers stop the check from loading. Test the form in the browsers your partners use before you recruit.

When to revisit your form

If quality is mixed, add a single-choice screening question. If applications are slow, cut a field and make the commission prominent.
