Most interventions require actions or logic to be performed as a result of participant data. This can be for adherence tracking, messaging, or more. There are several two main ways an intervention can be configured to be reactive to participant data.
...
Another way in which Way to Health enables you to perform actions based on your collected data is through Participant Data Variable. Once you have one of these variables defined, you can use it in messaging or logic.
Data Collection
There are two ways in which we collect data from a device. A vendor can either push data to Way to Health when they have something to provide to us (Push), or Way to Health can routinely ask the vendor if there are any updates (Pull). This doesn’t generally have an impact on how a study is built, but it does play into when exactly data comes into the platform, which can be useful for solving issues., logic, or other variables.

What’s the difference between “Timestamp” and “Received in W2H”? | Timestamp refers to when the vendor says the data is for. Received in W2H refers to when that data made it into the platform. Example: On 10/05/2023, a participant walked 8429 steps. On 10/06/2023, Way to Health asks Fitbit how far the participant walked the previous day. In Manage Data, the Timestamp will be some time during 10/05/2023 since that is when the data is for while Received in W2H will be some time on 10/06/2023 since that is when the data made it into W2H.How do I enable intraday data collect? | |
How do I change the field that attaches to a Collect Data event? | If there are multiple rows in manage data for a Collect Data event window, how do I change which value attaches? | |
What is device latency? | Device Latency is a period of time that Data Collection events will wait before closing to allow for data to be collected. This will usually allow a device to ensure all data for the previous day is in the platform before closing. | |
Why does data come in late? | How do I create an incident whenever late data is attached to a Collect Data event? |

There are a number of reasons that data may come in late, which depends on the device. Some common reasons for data to not come in, or come in late:
Both of these could cause delays in the data making it from the device to Way to Health. |
