Common Request Query Parameters for Web Services

Parameter NameTypeRequiredValidationsDescription

List of dimensions separated by a comma.

See Supported Dimensions below for details.

A list of comma-separated dimensions offered by respective web service.
If dimensions is not present in the query, the API will respond against all the dimensions supported by web service.
Important note:

  • Empty spaces are not allowed within the dimension list.
  • The parameter names in dimension, sort and filters are case sensitive.

List of dimensions separated by comma sorted by the criteria specified.

See Sort Functionality below for details.

A list of comma-separated dimensions to sort the returned records either in ascending or descending order.

You can sort in descending order by using a minus sign prefix on the requested sort field.

If your query is missing a sort key, the query returns a, "Bad Request" response with the error code, INVALID_SORT_KEY.


List of filters/conditions to perform condition search based on dimensions supported by Web service.

See  Filter Operators  below for details.

A single filter uses the form: name operator value
In the above syntax:

  • name = dimension name on which you have to apply the filter
  • operator = defines the type of filter match to use. Find more details on supported filter operations
  • value = states the values to be included in or excluded from the results.

Filter Types:

  • AND: Filter conditions passed in the request as multiple values for filters parameter use AND.
    For example: &filters=<dim1> EQ <value1>&filters=<dim2> EQ <value2> is interpreted is interpreted as (dim1= value1 AND dim2= value2).
  • OR: Comma( , ) separated filter conditions in the value of filters parameter use OR. For example: &filters=<dim1> EQ <value1>,<dim2> EQ <value2> is interpreted as (dim1= value1 OR dim2= value2).

Important notes:

  • There should be space between name, operator and value.
  • Operator are not case sensitive. For example, noteq and NOTEQ are considered the same.
pageNumberIntegerNoPage number to get data for a particular page. Default value is 1.Page number to get data for particular page. Default value is 1.
Providing zero or negative number will result in setting default value of 1.
pageSizeIntegerNoNumber of records to fetch on specific pageNumber. If pageSize is not specified, the default value will be 100.

Indicates the number of records returned from the API on specific page.
Providing zero or negative number would result in setting default value of 100.

Important Note: If pageNumber and pageSize parameters are not found in the request then pageNumber will be set as the default value of 1 and pageSize will be equal to totalRecords.

Supported Dimensions

Parameter NameTypeRequiredValidationsDescription

  2. Date and Time must be in  yyyy-MM-dd'T'HH:mm:ss 
    For example, 2016-06-01T00:00:00

Start date and time of the requested record will become active; for example, when a line item will begin delivering. You can also pass "now" rather than an explicit date to request ASAP.  The API sets dates based on the following conditions:

  1. If order start date is in the past, the query will return requested records based on the current date/time in the order's time zone.
  2. If order start date is in the future, the query returns requested records based on the order's start date/time in the order 's time zone.

For example:

  1. End date/time for the requested record; for example, the end date/time a line item is expected to complete.
  2. End date and Time should be greater than start date and time.
  3. End date should be less than or equal to order end date and time.
  4. Date and Time must be in  yyyy-MM-dd'T'HH:mm:ss

End date and time for a requested record.
  1. Should be valid and exists in the system.
  2. If you do not pass the lineItem type system will "Standard" as a type.

Type of Line Item. You can retrieve the line item types using Line Item Type API.

Based on line item type, you have to select valid goalType, goalPricing and goalUnit. Following table summarized the rules.

Line Item TypeGoal PricingGoal TypeGoal UnitDescription
SponsorshipCPM / CPCImpressionsPercentage% of total impressions (0 to 100%)
StandardCPMImpressionsAbsoluteNumber of impressions
 CPCClicks AbsoluteNumber of clicks
HouseCPM / CPCImpressionsPercentage% of remaining impressions
PMPCPMImpressionsPercentage% of remaining impressions
RTBCPMImpressionsPercentage% of remaining impressions
WrapperCPMNot ApplicableNot ApplicableGoal type and goal unit are not applicable

Note:For PMP type of line item, default priority is set to 5, but it could have priority in range of ( 5-16 ) while, for RTB type of line item, default priority is set to 8 ,but it could have priority in range of ( 8-16 ).

  1. Priority for the line item.
  2. You can assigned the priority depends on line item type. following table summarized the valid prioritize for respective line items.

Specifies the priority of a line item, relative to competing line items, in cases when inventory is over committed. Priorities can be applied to

Line Item TypePriority Range
Sponsorship1 - 4
Standard5 - 14
House13 - 16
Open Exchange8-16
  1. Status should be valid and exists.
  2. Default is "Draft" for newly created line item.
Status of the Line Item.

You can retrieve the list of status using Status API

Following status are supported for a Line Item -



9Completed11In Review
12Rejected 13 Failed

The system makes the Line Item active once user maps the creatives to that line item. This is valid only for guaranteed line item like Standards, Sponsorship and House.

For Programatic line items like ( Open Exchange, PMP ), the status of line item set to Active once created as user can not map the creative to this.

Status "In Review", "Failed" and "Rejected" is very specific and applicable to PMP type of line item and user can set it through API. However you can use "In Review", "Failed" and "Rejected" to apply filters and for searching Line item having this status.

  1. It should be valid and non negative.

The selected targeting criteria is set against the target id. You have to use this identifier to set the various targeting for given line item. Please refer to Phoenix API#LineItemTargetingServices

  1. It should be valid and non negative.

Describes how the line item is priced.

To retrieve the list of supported pricing model by Phoenix you can use Goal Pricing API

Pricing ModelDescription
1CPM: Cost per thousand impressions

CPC: Cost per click.

  1. Valid, non negative and should be greater than zero.

Defines the total goal of the line item. For guaranteed line items goal must be achieved. For non guaranteed achieving goals are not guaranteed however it is guaranteed to not exceed the goal.

Goal is closely tied to Pricing model and UI must ensure that. Example: If CPC pricing model is chosen goal is a whole number indicating number of clicks. If Share of Voice is chosen then goal is a whole number indicating percentage (1 - 100).

  1. Should be valid and exists.

Goal Unit. It could be either Absolute Number or in form percentage for the goal.

To retrieve the list of supported Goal Units by Phoenix you can use Goal Unit API

Goal UnitDescription
rateDouble upto 2 places of decimalYes
  1. Must be greater than or equal to 0 and less than/equal to 999999999.00
Represents the average rate ( ecpm) of the selected line item.
currencyCurrency ObjectNo
  1. Read Only
  2. Not expected in the request

Provides the information about unit in which rate value should be treated.

While creating the line item (POST method) API internally determines the Account / Network level currency  and sets the same currency for the line item.

For PMP Type of Line Item the currency will be always Dollar ( $) irrespective of your account level currency. 

Read-only attribute. It will be ignored If sent in requests. Attempting to change the value with a PUT/PATCH request returns a read-only attribute error.

  1. Read only
  2. Not expected in the request
It is the adUnitId against which the lineitem is targeted.
  1. Should be a valid value.
This specifies the type with which lineItem is targeted against the adUnit. It can have values viz. direct, inherited, RON.
  1. Read Only
  2. Not expected in the request and will always be returned by the API.
It specifies the timeZone in which lineItem will run. The timeZone is extracted from the order and if not found, extracted from the account.

Sort Functionality

Sort operates on a single dimension. Sorting by multiple dimensions is not supported by this API. Currently, custom sort functionality works only with object types:

  • primitives

  • Date
  • String
  • PubMaticEntity

The following attributes support sort functionality:

  • id
  • name
  • startDate
  • endDate
  • lineItemType
