Gravity Forms

License required

Gravity Forms is third-party Wordpress plugin. The integration requires you to purchase any license that enables you to use the Webhooks plugin. At the time of writing, the only license that enables that plugin, is Elite.

This guide uses the free Gravity Forms demo hosted on a temporary Wordpress instance. At the time of writing, demo instances will be running for 14 days.

The result of this guide is a form that captures contact details and self-assessment responses, and transmits this data to the Candidate API via Gravity Forms' webhook feature. This will be performed within a demo WordPress installation supplied by Gravity Forms. We will submit a candidate for a study named "Genericazeram Demo". The sequencing of questions and input fields will mirror those of a widget configured for demonstration objectives.

1. Creating a form

We will create a new Wordpress page where we will add our empty form.

1. Navigate to Forms in the Wordpress admin sidebar.
2. Click Add New
3. Select Blank form
4. Set the title to Genericazeram Demo and click Create Blank Form

2. Setup form fields

In the previous step we added an empty form. In this step we will be adding self-assessment questions, contact information and privacy consent field.

Study setup

Self-assessment questions:

1. Are you at least 30 years of age? (yes/no) [30_years]
2. Do you have a doctor's diagnosis of Parkinson's disease? (yes/no) [diagnosis]
3. Do your Parkinson's symptoms cause you to be wheelchair bound or bedridden? (yes/no) [wheelchair_bedridden]
4. Please rate the severity of your symtoms from Parkinson's disease. (scale: 1-5) [stiffness_shaking]

Candidate fields:

• Name
• Email
• Phone number
• Postal code
• Preferrer contact time
• Preferred contact method
• Data consent

Self-assessment

The editor provides a drag and drop interface, we will add the all components for self-assessment.

1. Click the Section in the field selector (right side of the screen)
2. Click the newly added element and change the title to "Contact information"
3. Now we will use three radio button fields to represent the first three questions asking yes/no questions.
   1. Click the Radio Button field on the right hand side.
   2. Click the newly added Untitled and update the field label and the choices to say "Yes" and "no" with the corresponding values "true" and "false".
   3. In the "rules" section, make the field required to add client-side validation.
4. Clone the age-question three times and update the title.
5. To represent the severity question of type scale, we will use a number input.
   1. Click the Number field on the right hand side.
   2. Click the newly added Untitled and update the field label.
   3. Set the range to be minimum, and maximum 5.
   4. In the "rules" section, make the field required to add client-side validation.
6. Done

Contact information

1. Click the Section in the field selector (right side of the screen)
2. Click the newly added element and change the title to "Contact information"
3. For contact information, we will be using Gravity forms advanced fields: Name, Email, Phone number and Postal code .
   1. Click Name
   2. Click the newly added Name. In the "rules" section, make the field required to add client-side validation.
4. Repeat the previous step for Email and `Phone number``. Remember to make them all required.
5. For Postal code, click Address
   1. Remove all sub-fields except for ZIP / Postal Code.
   2. In the "rules" section, make the field required to add client-side validation.

Data consent

Last, we must add input allowing the candidate to provide a consent to store their personal data.

1. Now we will use a radio button field to represent the consent yes/no question.
   1. Click the Radio Button field on the right hand side.
   2. Click the newly added Untitled and update the field label to "Consent" and the choices to say "Yes" and "no" with the corresponding values "true" and "false".
   3. In the "rules" section, make the field required to add client-side validation.

The editor should now look like:

4. Setup integration with Trialbee Honey

Gravity Forms supports sending entries to remote destinations using webhooks. In order to use this feature you first need to enable the plugin.

Enable webhook plugin

1. Using the Wordpress admin sidebar, select plugins.
2. Find the plugin called Gravity Forms Webhooks Add-On and press Activate.
3. Navigate back to the form we created before using the Forms-menu item
4. Hover the Genericazeram Demo and click settings.
5. Click webhooks.

We need to create a new webhook that will post entries to the Candidate API.

info

You need an API token for the next step. Contact your assigned Trialbee Project Manager to get one.

Setup webhook

1. Click Add new
2. Name the hook Trialbee Honey basic integration
3. Set the request URL to https://omniapi.trialbee.com?credential=<your API token here>
4. Leave request method as POST and format to JSON
5. Press Save settings

Map fields

We will stay in the webhook configuration page. In the Candidate API specification we outline blocks of similar information, i.e. candidate and selfAssessment. We can not fully use the OpenAPI specification while submitting the data to the API.

The API has an alternative dot-notation syntax which will make the integration with Gravity Forms straight forward. We need to map each form field to the corresponding API-field. In the request body, click the radio button Select Fields and start mapping them out.

Here are the mappings we will use

API-field	Data source
selfAssessment.answers.30_years	"Are you at least 30 years..."
selfAssessment.answers.diagnosis	"Do you have a doctor's..."
selfAssessment.answers.wheelchair_bedridden	"Do your Parkinson's..."
selfAssessment.answers.stiffness_shaking	"Please rate the severity..."
candidate.name	Name (Full Name)
candidate.email	Email
candidate.phoneNumber	Phone
candidate.postalCode	Address (ZIP / Postal Code)
consent.dataConsent	Privacy consent
attribution.referrer	site-{embed_post:post_title}
clientInformation.userAgent	{user_Agent}
clientInformation.referringUrl	Source Url

The idea for attribution.referrer is that we take the page name and make that the referrer. If you would have multiple referrers, and they all have their separate study page, you could use this as their identifier. For the example, it is however not important.

Save the form and the setup is complete! 🐝

5. Test

We have now completed all the steps and are therefore ready to try it out. Click Preview in top right corner of your form editor and you will see:

Submit details and it will be stored in Entries of Gravity Forms, but also sent via webhook to the API-endpoint.

Privacy & GDPR

Gravity Forms will store a copy of the submitted data by default. You must ensure that this is not against any privacy consent, GDPR or in breach with any relevant contract. Trialbee can only take responsibility for data submitted to the Candidate API and you must therefore ensure that you configure Gravity Forms accordingly.
