Add additional enrichments
Snowplow offers a large number of enrichments that can be used to enhance your event data. An enrichment either updates or populates fields of the atomic event or adds a self-describing context to derived_contexts.
The order of enrichments is hard-coded and cannot be changed, below table lists available enrichments in order they are executed.
| Enrichment | Description |
| IAB | Use the IAB/ABC International Spiders and Bots List to determine whether an event was produced by a user or a robot/spider based on its' IP address and user agent. |
| User Agent utils | Deprecated - please consider switching to YAUAA. |
| UA parser | Parse the useragent and attach detailed useragent information to each event. |
| Currency conversion | Convert the values of all transactions to a specified base currency using Open Exchange Rates. To use it, you need an Open Exchange Rates account. |
| Referer parser | Extracts attribution data from referer URLs. |
| Campaign attribution | Choose which querystring parameters will be used to generate the marketing campaign fields. If you do not enable the campaign_attribution enrichment, those fields will not be populated. |
| Event fingerprint | Generate a fingerprint for the event using a hash of client-set fields. Helpful for deduplicating events. |
| Cookie extractor | Specify cookies that you want to extract if found. |
| HTTP Header extractor | Specify headers that you want to extract via a regex pattern, if found each extracted header will be attached to your event. |
| Weather Enrichment | Unavailable since Enrich 1.4.x. |
| YAUAA | Parse and analyze the user agent string of an event and extract as many relevant attributes as possible using YAUAA API. |
| IP lookups | Lookup useful data based on a user's IP address using the MaxMind database. |
| JavaScript | Write a JavaScript function which is executed for each event. |
| SQL Query | Perform dimension widening on a Snowplow event via your own internal relational database. |
| API Request | Perform dimension widening on a Snowplow event via your own or third-party proprietary http(s) API. |
| IP anonymization | Anonymize the IP addresses found in the user_ipaddress field by replacing a certain number of octets with "x"s. |
| PII Pseudonymization | Better protect the privacy rights of data subjects by psuedoanonymizing collected data. |
