Please contact your account manager to get started. + +# Optable Targeting Module +{:.no_toc} + +* TOC +{:toc} + +## Overview + +The optable-targeting module enriches an incoming OpenRTB request by adding to the `user.eids` and `user.data` +objects. Under the hood the module extracts PPIDs (publisher provided IDs) from the incoming request's `user.ext.eids`, +and also if present sha256-hashed email, sha256-hashed phone, zip or Optable Visitor ID provided correspondingly in the +`user.ext.optable.email`, `.phone`, `.zip`, `.vid` fields (a full list of IDs is given in a table below). These IDs are +sent as input to the Targeting API. The received response data is used to enrich the OpenRTB request and response. +Targeting API endpoint is configurable per publisher. + +## Setup + +### Execution Plan + +This module runs at two stages: + +* Processed Auction Request: to enrich `user.eids` and `user.data`. +* Auction Response: to inject ad server targeting. + +We recommend defining the execution plan in the account config so the module is only invoked for specific accounts. See +below for an example. + +### Global Config + +In the host-level config you need to specify the regional endpoint that would be closest to the host: + +```yaml +hooks: + optable-targeting: + enabled: true + modules: + optable-targeting: + api-endpoint: https://na.edge.optable.co/v2/targeting?t={{TENANT}}&o={ORIGIN} +``` + +To obtain the endpoints for your regions - please contact [prebid@optable.co](mailto:prebid@optable.co). + +Note the endpoint contains 2 macros: {{TENANT}} and {ORIGIN} - the values for which are provided in the account-level config as `tenant` and `origin` parameters correspondingly. + +### Account-Level Config + +To start using current module in PBS-Java you have to enable module and add +`optable-targeting-processed-auction-request-hook` and `optable-targeting-auction-response-hook` into hooks execution +plan inside your config file: +Here's a general template for the account config used in PBS-Java: + +```yaml +hooks: + optable-targeting: + api-key: key + tenant: optable + origin: web-sdk-demo + ppid-mapping: { "pubcid.org": "c" } + adserver-targeting: true + cache: + enabled: false + ttlseconds: 86400 + host-execution-plan: > + { + "endpoints": { + "/openrtb2/auction": { + "stages": { + "processed-auction-request": { + "groups": [ + { + "timeout": 100, + "hook-sequence": [ + { + "module-code": "optable-targeting", + "hook-impl-code": "optable-targeting-processed-auction-request-hook" + } + ] + } + ] + }, + "auction-response": { + "groups": [ + { + "timeout": 10, + "hook-sequence": [ + { + "module-code": "optable-targeting", + "hook-impl-code": "optable-targeting-auction-response-hook" + } + ] + } + ] + } + } + } + } + } +``` + +### Timeout considerations + +The timeout value specified in the execution plan for the `processed-auction-request` hook is very important to be +picked such that the hook has enough time to make a roundtrip to Optable Targeting Edge API over HTTP. + +**Note:** Do not confuse hook timeout value with the module timeout parameter which is optional. The hook timeout value +would depend on the cloud/region where the PBS instance is hosted and the latency to reach the Optable's servers. This +will need to be verified experimentally upon deployment. + +The timeout value for the `auction-response` can be set to 10 ms - usually it will be sub-millisecond time as there are +no HTTP calls made in this hook - Optable-specific keywords are cached on the `processed-auction-request` stage and +retrieved from the module invocation context later. + +### Caching + +The module uses [Prebid Cache Storage](https://docs.prebid.org/prebid-server/features/pbs-pbc-storage.html) feature that relies on the existing Prebid Cache Server. By default it is disabled, but if enabled it caches Targeting API responses for ttlseconds (24 hours by default) which reduces the module processing time to milliseconds, rather than hundreds of milliseconds, for the cached Targeting API responses. + +## Module Configuration Parameters for PBS-Java + +The parameter names are specified with full path using dot-notation. F.e. `section-name` .`sub-section` .`param-name` +would result in this nesting in the JSON configuration: + +```json +{ + "section-name": { + "sub-section": { + "param-name": "param-value" + } + } +} +``` + +{: .table .table-bordered .table-striped } + +| Param Name | Required | Type | Default value | Description | +|:-------------------|:---------|:--------|:---------------|:---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| api-endpoint | yes | string | none | Host-Level. Optable Targeting Edge API endpoint URL. Note it must: include {{TENANT}} and {ORIGIN} macros that are substituted from account-level config values | +| tenant | yes | string | none | Account-Level. Your Optable tenant aka account ID. | +| origin | yes | string | none | Account-Level. Optable data `origin` aka `source`. | +| api-key | no | string | none | Account-Level. If the API is protected with a key - this param needs to be specified to be sent in the auth header | +| ppid-mapping | no | map | none | Account-Level. This specifies PPID source (`user.ext.eids[].source`) to a custom identifier prefix mapping, f.e. `{"example.com" : "c"}`. See the section on ID Mapping below for more detail. | +| adserver-targeting | no | boolean | false | Account-Level. If set to true - will add the Optable-specific adserver targeting keywords into the PBS response for every `seatbid[].bid[].ext.prebid.targeting` | +| timeout | no | integer | false | Account-Level. A soft timeout (in ms) sent as a hint to the Targeting API endpoint to limit the request times to Optable's external tokenizer services | +| id-prefix-order | no | string | none | Account-Level. An optional string of comma separated id prefixes that prioritizes and specifies the order in which ids are provided to Targeting API in a query string. F.e. "c,c1,id5" will guarantee that Targeting API will see id=c:...,c1:...,id5:... if these ids are provided. id-prefixes not mentioned in this list will be added in arbitrary order after the priority prefix ids. This affects Targeting API processing logic | +| cache.enabled | no | string | false | Account-Level. Optionally use [Prebid Cache Storage](https://docs.prebid.org/prebid-server/features/pbs-pbc-storage.html) feature - this significantly reduces the processing time when the Targeting API response has been cached | +| cache.ttlseconds | no | int | 86400 | Account-Level. The TTL in seconds for the Targeting API response to live in cache - by default is equal to 24 hours | + +## ID Mapping + +Internally the module sends requests to Optable Targeting API. The output of Targeting API is used to enrich the request +and response. The below table describes the parameters that the module automatically fetches from OpenRTB request and +then sends to the Targeting API. The module will use a prefix as specified in the table to prepend the corresponding ID +value when sending it to the Targeting API in the form `id=prefix:value`. + +See [Optable documentation](https://docs.optable.co/optable-documentation/dmp/reference/identifier-types#type-prefixes) +on identifier types. Targeting API accepts multiple id parameters - and their order may affect the results, thus +`id-prefix-order` specifies the order of the ids. + +{: .table .table-bordered .table-striped } + +| Identifier Type | OpenRTB field | ID Type Prefix | +|--------------------------------------------------------------------------------|-----------------------------------------------------------------------|------------------------------------------| +| Email Address | `user.ext.optable.email` | `e:` | +| Phone Number | `user.ext.optable.phone` | `p:` | +| Postal Code | `user.ext.optable.zip` | `z:` | +| IPv4 Address | `device.ip` | ~~i4:~~ Sent as `X-Forwarded-For` header | +| IPv6 Address | `device.ipv6` | ~~i6:~~ Sent as `X-Forwarded-For` header | +| Apple IDFA | `device.ifa if lcase(device.os) contains 'ios' and device.lmt!=1` | `a:` | +| Google GAID | `device.ifa if lcase(device.os) contains 'android' and device.lmt!=1` | `g:` | +| Roku RIDA | `device.ifa if lcase(device.os) contains 'roku' and device.lmt!=1` | `r:` | +| Samsung TV TIFA | `device.ifa if lcase(device.os) contains 'tizen' and device.lmt!=1` | `s:` | +| Amazon Fire AFAI | `device.ifa if lcase(device.os) contains 'fire' and device.lmt!=1` | `f:` | +| [NetID](https://docs.prebid.org/dev-docs/modules/userid-submodules/netid.html) | `user.ext.eids[].uids[0] when user.ext.eids[].source="netid.de"` | `n:` | +| [ID5](https://docs.prebid.org/dev-docs/modules/userid-submodules/id5.html) | `user.ext.eids[].uids[0] when user.ext.eids[].source="id5-sync.com"` | `id5:` | +| [Utiq](https://docs.prebid.org/dev-docs/modules/userid-submodules/utiq.html) | `user.ext.eids[].uids[0] when user.ext.eids[].source="utiq.com"` | `utiq:` | +| Optable VID | `user.ext.optable.vid` | `v:` | + +### Optable input erasure + +**Note**: `user.ext.optable.email`, `.phone`, `.zip`, `.vid` fields will be removed by the module from the original +OpenRTB request before being sent to bidders. + +### Publisher Provided IDs (PPID) Mapping + +Custom user IDs are sent in the OpenRTB request in the +[`user.ext.eids[]`](https://github.com/InteractiveAdvertisingBureau/openrtb2.x/blob/main/2.6.md#3227---object-eid-). +The `ppid-mapping` allows to specify the mapping of a source to one of the custom identifier type prefixes `c`-`c19` - +see [documentation](https://docs.optable.co/optable-documentation/dmp/reference/identifier-types#type-prefixes), f.e.: + +```yaml +ppid-mapping: {"example.com": "c2", "test.com": "c3"} +``` + +It is also possible to override any of the automatically retrieved `user.ext.eids[]` mentioned in the table above (s.a. +id5, utiq) so they are mapped to a different prefix. f.e. `id5-sync.com` can be mapped to a prefix other than `id5:`, +like: + +```yaml +ppid-mapping: {"id5-sync.com": "c1"} +``` + +This will lead to id5 ID supplied as `id=c1:...` to the Targeting API. + +## Analytics Tags + +The following 2 activities are recorded by the module in the corresponding ATags on the corresponding stages: + +* `optable-enrich-request` +* `optable-enrich-response` + +The `status` is either `success` or `failure`.
