# Returns all traffic sources with their configuration.

`GET /traffic-source`

Returns the list of traffic sources configured in the account, including their
custom variable name mappings, postback URLs, and cost tracking settings.

## Custom variable names

Each traffic source defines customVariable1Name through customVariable10Name,
which give meaning to the customVariable1-10 dimensions in reports.
The same index can mean completely different things on different traffic sources
(e.g. customVariable1 might be "Site ID" on one source and "Keyword" on another).

Read the variable name mappings from this endpoint before interpreting
groupBy=customVariable{N} report data. Cache the result — it rarely changes.

## Other fields relevant to report analysis

- postbackUrl — the URL used to fire conversions back to the traffic source
- costVariable — if present, the source passes cost data automatically

## Query parameters

- `includeDeleted` boolean
- `fields` string[]

## Headers

- `If-Modified-Since` string, date-time

## Response `200`

List of Traffic Sources.
