# Passing Respondent Data

> Append profiling and qualification data to entry links so Research Desk can relay live quota requirements.

Suppliers are asked to pass data points for each respondent into the Stream/Survey entry link. This helps Research Desk relay live sub-quota requirements back to you and enhances reporting and monitoring.

## 1. Default Profiling

Suppliers are required to pass basic profiling information for each respondent into the entry link:

| Profiling Point        | Requirement                                                                      |
| ---------------------- | -------------------------------------------------------------------------------- |
| Age                    | Required for all countries and languages.                                        |
| Gender                 | Required for all countries and languages.                                        |
| Income                 | Required for all countries and languages.                                        |
| Zip Code               | 5 digits for US, 3 chars for UK, 3 chars for Canada; others on a per-case basis. |
| Ethnicity              | Required for US only; optional for others.                                       |
| Hispanic/Latino Origin | Required for US only.                                                            |

Each profiling point corresponds to a Qualification question from the [Qualification Library](https://docs.repdata.com/supply/endpoints/get-v2-qualifications). Pass the data into entry links using the format where the **Global Qualification Number** is the link variable name and the **Precode** is the numerical value of the answer choice.

Example variable passing for a respondent from the United States:

| Profiling Point | Global Qualification Number | Answer          | Precode |
| --------------- | --------------------------- | --------------- | ------- |
| Age             | `42`                        | Age 35          | `35`    |
| Gender          | `43`                        | Female          | `2`     |
| Income          | `14785`                     | $25,000–$29,999 | `6`     |
| Zip Code        | `45`                        | 70115           | `70115` |
| Ethnicity       | `113`                       | Black           | `2`     |
| Hispanic        | `47`                        | No              | `1`     |

The resulting entry link would be formatted as follows (profiling appended to the base link returned by the Create Links endpoint):

```text theme={null}
https://www.rdsecured.com/landing2?fttsn=83b4a586-ad4f-4762-acbb-8cd0b9fe21fe&rid=ABC&pid=XYZ&panel=Panel1&42=35&43=2&14785=6&45=70115&113=2&47=1
```

## 2. Other Qualifications (per-case)

Any additional qualifications or profiling implemented on a Stream must also be appended to the entry link. For example, if a Stream is qualifying on pet owners who own dogs, append `&639=2`:

```text theme={null}
https://www.rdsecured.com/landing2?fttsn=83b4a586-ad4f-4762-acbb-8cd0b9fe21fe&rid=ABC&pid=XYZ&panel=Panel1&42=35&43=2&14785=6&45=70115&113=2&47=1&639=2
```

## 3. Multi-Select Questions

For multi-punch questions, separate answer choices with a pipe (`|`). For example, pet owners who own dogs, cats, and reptiles would be appended as `639=1|2|7`:

```text theme={null}
https://www.rdsecured.com/landing2?fttsn=83b4a586-ad4f-4762-acbb-8cd0b9fe21fe&rid=ABC&pid=XYZ&panel=Panel1&42=35&43=2&14785=6&45=70115&113=2&47=1&639=1|2|7
```

## 4. Panelist ID

In addition to the Respondent Session ID (`rid`), suppliers are requested to provide a Panelist ID (`pid`) on the entry link, as shown in the examples above.

<Tip>
  Use the [Qualification Library](https://docs.repdata.com/supply/endpoints/get-v2-qualifications) and [Qualification Library Options](https://docs.repdata.com/supply/endpoints/get-v2-qualifications-options) endpoints to map your internal profiling values to Research Desk Global Qualification Numbers and precodes.
