Examples
The following examples demonstrate common Conversations API display requests. For a complete overview of using the Conversations API to display data, refer to the Display tutorials.
Demonstration purposes only. Do not reuse the API passkeys below in your application.
Requesting all reviews for a particular product
This example call shows how to use multiple filters. This call only returns the reviews that have comments on them. The reviews are sorted in descending order by Rating.
https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4&Filter=ProductId:data-gen-moppq9ekthfzbc6qff3bqokie&Sort=Rating:desc&Limit=10
Requesting all reviews for a particular product with review statistics (inc. average rating)
This example call shows how to use the include and stats parameters to retrieve product information and review statistics (including average rating). Note: Stats=Reviews must be used in conjunction with Include=Products.
https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4&Filter=ProductId:data-gen-moppq9ekthfzbc6qff3bqokie&Include=Products&Stats=Reviews
Requesting a single review by review ID for a particular product
https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4&filter=id:16970607
You can request multiple reviews by separating the review IDs with a comma.
- e.g. filter=id:83,84,85
Requesting a single review by review ID including product information for a particular product
https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4&filter=Id:16970607&include=Products
You can request multiple pieces of information by separating them with a comma.
- e.g. Include=products,categories,authors
Requesting 20 reviews, sorted by rating in ascending order for a particular product
https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4&Filter=ProductId:data-gen-moppq9ekthfzbc6qff3bqokie&Sort=Rating:desc&Limit=20
You can sort by multiple attributes by separating them with a comma - e.g. Sort=Rating:desc,SubmissionTime:asc
Requesting Reviews using Relevancy Sort
Relevancy Sort must not be used with any other sort, it is currently not supported.
https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4&Filter=ProductId:data-gen-moppq9ekthfzbc6qff3bqokie&Sort=relevancy:a1&Limit=20
Requesting reviews using a filter and returning statistics for the filtered results for a particular product
https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4&Filter=ProductId:data-gen-moppq9ekthfzbc6qff3bqokie&Include=Products&FilteredStats=Reviews&Filter=HasPhotos:eq:true
You can get statistics specific to the filter applied to a request using the "&FilteredStats" parameter
Requesting all native (non-syndicated) reviews
Native (non-syndicated) content only.
https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4
Requests for this content type that do not include a ProductId, AuthorId, CategoryAncestorId, SubmissionId, or Review Id filter will only work with API keys that are configured to exclude syndicated content.
We recommend using our Displayable Content Export service to download all of your native and syndicated content. If you still prefer the Conversations API, then you may contact our support team to have your Conversations API keys re-configured.
Requesting reviews for a product that is associated with a product family
https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4&Filter=ProductId:data-gen-a718alq7rap86nqc7v05h304x&include=products
The product families feature allows you to share reviews among related products. Learn more about product families at the Bazaarvoice Knowledge Base.
The parameter “include=products” will result in the API returning product information in the response. This information can be used to identify about which product a review was originally written. Use the ‘ProductId’ field on
each review to look up the relevant product information in the “Includes.Products” object.
You will notice that several reviews in the response are associated with "Product4" despite using a filter in Request for ProductId:data-gen-a718alq7rap86nqc7v05h304. That’s because these products are in a product family. The ProductId:data-gen-a718alq7rap86nqc7v05h304 and Product4 are associated with a product family and therefore returning the reviews associated with both the products.
Parameters
| Name | Description | Required | Default Value |
|---|---|---|---|
ApiVersion | The API version, e.g. 5.4. | Yes | |

Filter options
- Each filter argument specifies the attribute to filter on followed by a comma-separated list of values. For instance, "
Filter=Rating:eq:3,4" will match all reviews with rating values 3 OR 4. - Advanced operators can be used to define filters. For instance, "Filter=Rating:lt:3" will match all reviews with a rating value less than 3. All advanced operators are documented on the Conversations API page.
- If a filter value contains a comma or a colon, that character needs to be escaped with a backslash (, or :). If a filter value contains an ampersand (&), the ampersand must be encoded in the filter value by replacing & with %26.
- Multiple filters are allowed as URL parameters in which case filters are AND'ed. For instance, "
Filter=Rating:gte:4&Filter=IsFeatured:eq:true" will match all featured reviews with a rating of 4-star or higher. - Time-based filters can be used for SubmissionTime, LastModificationTime and LastModeratedTime. Dates in time-based filters are calculated as the number of seconds since January 1, 1970, 00:00:00 UTC. In a future version, we will be adding support for comparing date/time string values. The following example returns content that was submitted on November 9, 2009:
&filter=SubmissionTime:gt:1257746400&filter=SubmissionTime:lt:1257832800
The following table lists the attributes available for filtering.
| Name | Description |
|---|---|
Id | The identifier of the Review. |
AdditionalField_[FIELD_NAME] | Additional field to filter by, e.g., filter=AdditionalField_[FIELD_NAME]:eq:[FIELD_VALUE] |
AuthorId | The identifier of the author who wrote the content |
CampaignId | The identifier of the Campaign associated with the content |
CategoryAncestorId | The identifier of the Product Category ancestor of the Product that the Review was written on. Syndicated content will not be returned when using this filter. |
ContentLocale | Locale of the content to display. If this filter is not defined, all content regardless of its locale is returned. To return specific content by locale, define the value in the filter. A wildcard character “*” can be used to define the value, e.g., “en*” returns all content in English (en_US, en_CA, en_GB, etc.) or you can use a single ContentLocale code (e.g., “fr_FR”). ContentLocale codes are case-sensitive. |
ContextDataValue_[DIMENSION_EXTERNAL_ID] | The context data value for the content. DIMENSION_EXTERNAL_ID can be age, gender, etc. e.g. filter=contextdatavalue_age:under21 |
HasMedia | Boolean flag indicating whether content has either photos or videos |
HasPhotos | Boolean flag indicating whether content has photos |
HasTags | Boolean flag indicating whether content has tags |
HasVideos | Boolean flag indicating whether content has videos. |
Helpfulness | Helpfulness represents how helpful a review has been to consumers. The Helpfulness value takes into account several factors including feedback votes and how many approved reviews an author has written. It will be a positive decimal value between 0 - 1.0, or null if not enough data exists to calculate it. |
IsFeatured | Boolean flag indicating whether content is featured |
IsRatingsOnly | Boolean flag indicating whether the review was a ratings only review |
IsRecommended | Boolean flag indicating whether the user would recommend this product |
IsSubjectActive | Boolean flag indicating whether the content subject is active |
IsSyndicated | Boolean flag that allows you to select whether to return syndicated or non-syndicated reviews. If IsSyndicated:eq:true, the response only returns syndicated content and a SyndicationSource block with the details of where the syndication is coming from. If IsSyndicated:eq:false, the response only return native (non-syndicated) content. Note: The API key must be configured to show syndicated content. |
LastModeratedTime | The date/time of the latest moderation of the content. See the Introduction for an example of using advanced operators for filtering. |
LastModificationTime | The date/time of the latest modification of the content. See the Introduction for an example of using advanced operators for filtering. |
ModeratorCode | String value indicating the moderator code for content that was at one time rejected e.g., &Filter=ModeratorCode:eq:CR returns UGC that contains the CR (Competitor Reference) code. Multiple codes can be entered in a comma-delimited list, e.g., &Filter=ModeratorCode:eq:CS,IU returns UGC with either the CS (Customer Service Complaint) or the IU (Inappropriate/Unusable Content) code. For a list of all Moderator Codes, see the Conversations API page. Note that the ModeratorCodes attribute parameter should be included in the request. This will ensure the moderated code(s) for each request will be included in the response. If the ModeratorCodes attribute is missing the filter will still perform, but there is not indication of which elements have been tagged with which codes. See the Parameters section above. A more detailed discussion on how moderation works can be found here. |

ERROR_PARAM_INVALID_OFFSET | Invalid offset value |
ERROR_PARAM_INVALID_SORT_ATTRIBUTE | Invalid sort attribute name |
ERROR_REQUEST_LIMIT_REACHED | Rate limiting error, i.e. too many requests per time interval |
ERROR_UNKNOWN | Unknown error (internal server error, for instance) |
By default, for all the form errors occurred during the API calls, the HTTPS response code 200 OK is returned, with the error information in the JSON response body.
curl --location 'https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4k&Filter=ProductId%3Adata-gen-moppq9ekthfzbc6qff3bqokie&Include=Products&Stats=Reviews'
If the clients wish to receive 4xx, 5xx kind of error codes in HTTPS response, a small addition needs to be made to the api call. In the request header of the API call, add "bv-version" with value "5.4.1", this will generate appropriate 4xx, 5xx error codes in the HTTPS response. The JSON response still contains the detailed description of the error.
Example curl with header:
curl --location 'https://stg.api.bazaarvoice.com/data/reviews.json?apiversion=5.4&passkey=caB45h2jBqXFw1OE043qoMBD1gJC8EwFNCjktzgwncXY4k&Filter=ProductId%3Adata-gen-moppq9ekthfzbc6qff3bqokie&Include=Products&Stats=Reviews' \
--header 'bv-version: 5.4.1'
