### Everflow SDK Overview
[SDK Documentation](https://developers.everflow.io/docs/everflow-sdk/)
[Conversion Methods Documentation](https://helpdesk.everflow.io/en/articles/3705654-direct-linking-and-conversion-tracking-methods)

### Structure
All Attribution settings can be managed from offer to offer. 

### First Click / Last Click Attribution
Everflow allows clients to select if they would like to attribute the conversion to partner that receives the first or last click. 

**Examples**
First Click - User A clicks Partner A's link and is taken to www.everflow.io. We register a cookie on www.everflow.io. User A leaves the page and then clicks Partner B's link and lands on www.everflow.io and then buys. **Partner A** gets credit for the conversion. 

Last Click - User A clicks Partner A's link and is taken to www.everflow.io. We register a cookie on www.everflow.io. User A leaves the page and then clicks Partner B's link and lands on www.everflow.io and then buys. **Partner B** gets credit for the conversion. 

### Cookie Windows
Our cookie is set for 90 days. Everflow clients do have the ability to set a window that is less than 90 days at the offer level. The conversion will still come in and get attributed based on first or last click attribution. We will just reject the conversion automatically if it is over the window. 

**Examples**
No window set - User A clicks Partner A's link and is taken to www.everflow.io. We register a cookie on www.everflow.io. User A leaves the page and then comes back within 90 days, Partner A will get credit. On day 91 the conversion will not come into Everflow at all. 

Window set to 30 days - User A clicks Partner A's link and is taken to www.everflow.io. We register a cookie on www.everflow.io. User A leaves the page and then comes back within 30 days, Partner A will get credit. On day 31 the conversion will come into Everflow but be sent to rejected. 

Edge case window set to 30 days, first click - User A clicks Partner A's link and is taken to www.everflow.io. We register a cookie on www.everflow.io. User A leaves the page and then clicks Partner B's link on day 31 and lands on www.everflow.io and then buys. **Partner A** gets credit for the conversion but it is set to rejected inside Everflow. (Partner B doesn't get credit even though it is past the window set inside Everflow) 

### Email Attribution, First & Last
Everflow has the ability to attribute a conversion if no cookie is found by using an email that was sent to our system via a cookie based conversion previously. We look up the previous conversion with that email and give credit to either the first partner or last partner that sent that email based on the setting.
