Query strings are powerful tools for transferring data within URLs, offering a streamlined means to convey information across web applications and platforms. Leveraging query strings facilitates data transmission within a URL and enables seamless information exchange during redirects, such as in forms.
Employing query strings within trigger links streamlines the process of passing essential information to forms efficiently. To integrate query strings effectively, follow these straightforward steps:
Navigate to the Appropriate Form: Access the desired form within the sites tab.

Select Fields for Data Transfer: Identify the fields whose information you intend to pass. Click on each field to access the Query String option within the right-side menu. Repeat this step for all pertinent fields. Eg, for the contact’s first name:

Retrieve Form URL: Proceed to click on the “Integrate” button located at the top of the form interface to acquire the form’s URL.

Incorporate Trigger Links: Head to the Marketing tab, then select Trigger Links to create a new one. Paste the previously obtained form URL into the designated area.

Configure Query String Parameters: Customize the trigger link by appending query string parameters for each field to the form’s link. For instance, to pass the contact’s first name, incorporate the query string retrieved from the form followed by the desired value to the end of the form’s link in the trigger link. Syntax: ?first_name={{contact.first_name}}. To include additional fields, use the ‘&’ symbol to separate each parameter, maintaining the same syntax.

Complete Configuration: Finalize the trigger link setup by accurately including query string parameters for all desired fields. eg. If you want to pass the last name field as well, you will need to add & and follow the same syntax

Streamlining Data Transmission with a Simple Syntax
Adhering to a straightforward syntax ensures the seamless integration of query strings within URLs. Follow these guidelines to incorporate query strings effectively:
By using query strings, you can make navigating the web a whole lot easier and faster, especially when it comes to filling out forms.
Note: Query String will pass the information of only existing contacts, if you’re sending the trigger link to a client whose contact is not created in your account, it will not pass any information. It fetches information from the existing contacts.

Question: Can I use query strings to pass multiple data fields in one URL?
Answer: Yes, you can pass multiple data fields using query strings by separating each parameter with the ‘&’ symbol. For example, to pass both the first and last names, your URL would look like this: ?first_name={{contact.first_name}}&last_name={{contact.last_name}}.
Question: Will query strings work for new contacts that are not in my account?

Question: Why is it important to adhere to proper query string syntax?
Answer: Adhering to the correct syntax for query strings ensures that the data is passed accurately and that URLs function as intended. Incorrect syntax can result in errors or failure to transfer data, disrupting the intended workflow.
Question: What should I do if the query string isn’t passing data correctly?

Question: Is there a limit to how long a URL can be with Query Strings?**
**Answer: While most modern browsers can handle very long URLs (up to 2,000+ characters), it is best practice to only pass necessary information. Passing dozens of fields can make the link look messy and increases the slight risk of the URL being “clipped” in some email mobile apps.
Question: How do I handle multiple fields when building my custom URL?
Answer: To include multiple parameters, you must use the ‘?’ symbol only for the first parameter. For every additional field you wish to pass (such as adding a last name after a first name), you should use the ‘&’ symbol to separate them.
