Authorizations

Authorization

string

header

required

Authenticate every request with a Bearer token. Pass your Reply API key in the Authorization header:

Authorization: Bearer <your-api-key>

Get your API key from the Reply dashboard: Settings → API Key.

Body

application/json

Request body shared by both /estimate and /schedule. Specifies the contacts to validate and an optional partial-credit acceptance flag.

contactIds

integer[]

required

Contact IDs to validate. Must be non-empty, contain at most 10000 items, and every value must be a positive integer.

Required array length: 1 - 10000 elements

Required range: x >= 1

acceptPartial

boolean | null

When true, the schedule call proceeds with min(eligibleCount, creditsAvailable) contacts even if available credits are below the eligible count. When false (default), insufficient credits become a NotEnoughCredits blocker on /estimate and a 400 on /schedule.

Response

Estimate computed successfully

Synchronous probe result returned by /v3/email-validations/estimate. Reports counts, credit sufficiency, and a list of blockers that prevent scheduling.

requestedCount

integer

read-only

Total number of contact IDs in the request body

eligibleCount

integer

read-only

Number of contacts the user can actually validate (filtered by team scope and validation-status)

creditsAvailable

integer

read-only

Email-validation credits currently available to the team

creditsRequired

integer

read-only

Credits that would be charged if the eligible contacts are scheduled in full

creditsSufficient

boolean

read-only

Whether creditsAvailable >= creditsRequired

canSchedule

boolean

read-only

Whether the request can be scheduled — equivalent to blockers.length == 0

blockers

enum<integer>[]

read-only

Reasons why scheduling is currently blocked. Empty when canSchedule is true.

Blocker codes returned by /v3/email-validations/estimate in the blockers array. The presence of any blocker (with acceptPartial = false) means the request cannot be scheduled.

Value	Name	Meaning
1	`FeatureDisabled`	Email validation feature is disabled for the team
2	`AddonNotPresent`	Required addon is not on the subscription
3	`AlreadyRunning`	Another email-validation job is already running for this user
4	`OutOfCredits`	User has no email-validation credits available
5	`NotEnoughCredits`	Available credits are below the eligible-contact count (and `acceptPartial = false`)
6	`NoEligibleContacts`	No accessible contacts in `RequiresValidation` state were found in the request
