Authorizations

Authorization

string

header

required

OptimalDial API key, prefixed od_live_, sent as Authorization: Bearer .... Mint keys in the in-app developer panel; they are scoped to a single organization.

Body

Requires file plus either phone_column or phone_columns. Supplying both is allowed only when they agree.

file

required

CSV file (≤100 MB, must include a header row).

phone_column

string

Name of the column containing phone numbers. Use this OR phone_columns.

phone_columns

string

Comma-separated names of up to 10 columns containing phone numbers, e.g. mobile,direct. Every number is validated and billed separately, so a contact with a number in two mapped columns costs 2 credits (3 at max). The same number appearing in several columns is charged once. Results come back as one row per contact with a {column}_OptimalDial_Status column per mapped column. A column name containing a comma cannot be expressed here — use JSON mode, where this is a real array.

skip_mobile_lookup

boolean

default:false

validation_tier

enum<string>

default:standard

Validation tier. standard charges 1 credit/contact; max is more thorough and charges 1.5 credits/contact (billed as ceil(valid_count × 1.5)).

Available options:

standard,

max

filename_override

string

Override the file's original name.

full_name_column

string

Enables OptimalDial Identity. Name of the column holding the contact's full name. Supply this OR both first_name_column and last_name_column.

first_name_column

string

Enables OptimalDial Identity when supplied together with last_name_column. Supplying only one half returns 400.

last_name_column

string

Enables OptimalDial Identity when supplied together with first_name_column. Supplying only one half returns 400.

Response

Upload created, credits charged, ready for processing.

string<uuid>

required

user_id

string<uuid>

required

original_filename

string

required

status

enum<string>

required

cancelled is a legacy value retained so historical uploads still parse — no new upload can enter it.

Available options:

pending_mapping,

validating,

validation_failed,

awaiting_confirmation,

ready_for_processing,

processing,

completed,

failed,

cancelled

created_at

string<date-time>

required

updated_at

string<date-time>

required

organization_id

string<uuid> | null

file_size_bytes

integer | null

valid_row_count

integer | null

Contact rows processed.

valid_number_count

integer | null

Billable phone numbers. Equals valid_row_count when one phone column is mapped; larger when several are. This is the count credits are charged on, so do not derive an invalid count by subtracting it from validation_results.total_rows.

invalid_row_count

integer | null

credits_required

integer | null

credits_charged

integer | null

credits_refunded

integer | null

Credits returned to the organization when OptimalDial refunds an upload.

source

enum<string> | null

web for in-app uploads, api for direct /api/v1/uploads calls, api_pool for uploads synthesized from the Contacts API.

Available options:

web,

api,

api_pool,

null

api_key_id

string<uuid> | null

skip_mobile_lookup

boolean | null

validation_tier

enum<string> | null

Validation tier used for this upload (standard or max).

Available options:

standard,

max,

null

identity_enabled

boolean | null

Whether OptimalDial Identity was requested for this upload, i.e. a name column was mapped at creation.

result_summary

object | null

Distribution of the results, populated once status == "completed". Lets you see the shape of a list without downloading it.

Show child attributes

export_count

integer

How many times these results have been downloaded, counting both the web app and this API.

last_exported_at

string<date-time> | null

processed_available

boolean

true once the processed file can be downloaded. Storage keys are deliberately not exposed — use the download endpoints.

processed_filtered_available

boolean

true once the deprecated download/processed-filtered endpoint will succeed, whether from a stored file or generated on demand.

error_message

string | null

exceeded_daily_limit

boolean | null

true if this upload was submitted after your organization had already used its plan's daily processing capacity, measured in phone numbers on a midnight America/New_York day boundary. Advisory only — the upload is accepted and processed in full, and the remainder carries into the next processing day at no extra charge. Before 2026-09-04 this was measured per uploading user and per UTC day.
